Most pellet grills are built to live outside, but they are not built to sit in snow for five months without any protection. Moisture pools in the grease channel and ash pan, condensation forms under the hopper lid, and freeze-thaw cycles crack cheap fabric and fade powder coat. Finding the best pellet grill covers for winter comes down to three things: an accurate fit, a heavy denier, and a fastening method that survives wind.
We spent weeks comparing ten of the highest-rated covers on the market, checking the fabric weight, stitching, vents, strap type and model fit for each one. Every cover below is written for a specific grill, so the first thing to do is confirm your grill model is actually on the fit list before you read anything else.
If you also run a grill through the cold months, our generator cover guide covers the same weatherproofing logic for a different machine. And if you are planning a full cold-weather cooking setup rather than storage, the cold-weather gear picks in our thermal underwear review matter as much as the cover does.

Should You Cover Your Pellet Grill in Winter?
Yes, if your grill stays outdoors, and the grill must be completely dry when you pull the cover on. A cover keeps rain, snow and UV off the metal while air vents or breathable fabric let trapped moisture escape, and the cover does nothing useful at all if you seal in a wet surface. Let the grill cool, wipe it down, cover it loose, and tighten the straps.
The main exception is a grill already stored under a roof, in a garage, or inside a shed. Covering a dry indoor grill is optional rather than necessary.

1. SHINESTAR 900D Oxford Cover for Pit Boss 820 and 850 Series
SHINESTAR Grill Cover for Pit Boss 850DX&820 Deluxe, 900D Oxford Waterproof
900D Oxford fabric
Reinforced double stitching
Drawstring hem and zipper
60 by 27 by 50 inch
Pros
- Heaviest fabric in this group at 900D Oxford
- Reinforced double stitching at every seam
- Drawstring hem plus full-length side zipper for quick on and off
- Fade-resistant surface wipes clean with a damp cloth
Cons
- Does not fit Pit Boss Austin XL or vertical smokers
- Runs loose on Pit Boss 1000 Series grills without an attached side smoker
Of everything we looked at, this is the cover we would put on our own Pit Boss 850DX. The 900D Oxford is the heaviest fabric in this group, and that extra weight is exactly what you want when a cover spends four months taking snow load and 30 mph gusts off a patio.
The double stitching is the detail that separates it from covers in the same class. Stitching is where covers fail first, so reinforced seams matter more than almost any other spec on the list. The full-length side zipper is unusually practical, since you can uncover a grill in seconds on a cold morning instead of wrestling a drawstring with gloves on.
Roughly 9400 reviews at an average of 4.7 stars gives this the broadest owner evidence base in the group, and the review pattern is consistent: heavy build, secure fit, easy to clean. That consistency matters more than any single specification when you are trusting a cover with a grill that costs far more than the cover does.
What to check before you buy
The fit list is long and specific, covering the 820 Deluxe, PB820PS1, Sportsman 820, Competition 820, Pro Series 850, 850 DX and Competition 850. Verify your exact model number rather than assuming your grill is in the 820 or 850 family, because Pit Boss reuses similar-looking cabinets across series.
This cover is explicitly not for the Austin XL, the 1000S, the 1100 Pro or any vertical smoker. If you own one of those, the QuliMetal Austin XL cover or the Pit Boss 5-Series cover is the right place to look.
Where it falls short
Owners running Pit Boss 1000 Series grills without an attached side smoker report a loose fit, since the cover is cut for the shorter 820 and 850 footprint. That shows up in wind first, and a cover that lifts at the hem is a cover that will be in a neighbour’s yard after the first storm.
The black material also absorbs heat in summer, which matters if you keep the cover on year-round rather than taking it off between seasons. Store it folded somewhere dry if you take it off for the summer.
2. QuliMetal 600D Cover for Recteq 590 and Deck Boss Grills
Grill Cover for Recteq 590/Deck Boss 590/800/900 Wood Pellet Grill
600D Oxford fabric
Custom fit for Recteq and Deck Boss
Air vents reduce condensation
Elastic drawstrings
Pros
- Custom sizing for Recteq RT-590 and Deck Boss 800 and 900
- 600D Oxford that is waterproof UV-protected and crack-resistant
- Elastic drawstrings keep the cover from blowing off
- Air vents reduce condensation and rust risk
Cons
- Sizing applies only to listed Recteq models
- Reflective tape is a minor add-on rather than a core feature
The vent is the reason we picked this one for Recteq owners. Most covers trap moisture against the barrel and hopper, and the metal underneath quietly corrodes through a winter. Strategic air vents let that moisture escape instead, which is the single most useful thing a pellet grill cover can do.
Sizing here is model-specific rather than generic, at 45 inch wide by 22 inch deep by 41 inch high, and it covers the Recteq RT-590, the Deck Boss 590, 800 and 900, and the Backyard Beast 1200. That precision is what stops the flapping that ruins generic covers in wind.
Elastic drawstrings at the base cinch the hem down tight, and the reflective tape makes the grill easier to find in a dark yard. Nearly 7000 reviews averaging 4.6 stars is strong evidence that the fit holds over time rather than just out of the box.
What to check before you buy
Confirm that your grill is a Recteq RT or Deck Boss model. The cover is cut to those shapes and will not suit a different brand, no matter how similar the cabinet looks, so measure against the listed cover size of 45 by 22 by 41 inch.
If your Recteq is a Flagship or RT-680, skip to the Uniflasy cover later in this list. It covers that range instead.
Where it falls short
The cover runs snug on some grills, which is a good thing in wind but tight if you like to reach underneath to check the grease channel without pulling the whole cover off.
Reflective tape is a nice touch for locating a grill in the dark, but it is an add-on rather than a feature that affects winter performance. Judge this cover on the vents and the fit.
3. Traeger BAC503 Full-Length Cover for Pro 575 and Pro 22
Traeger Grills BAC503 Full-Length Grill Cover Grill Accessory – Pro 575/ Pro 22, Black
Form-fitted OEM design
All-weather polyester
Water-resistant finish
UV-resistant coating
Pros
- Highest rating in this group at 4.9 stars
- Form-fitted to the Traeger Pro 22 and Pro 575
- All-weather polyester with a water-resistant finish
- Easy to put on and take off
Cons
- Carries the highest OEM premium in this group
- Fits only the Pro 22 and Pro 575 models
At 4.9 stars across more than 5500 reviews, this is the highest-rated cover we evaluated, and the satisfaction pattern behind that number is unusually clean. Owners talk about a perfect fit, a premium build, and covers that have held up for five-plus years without cracking or fading, even in direct sun.
It is a genuine form-fitted OEM cover, which is why it looks and feels different from a baggy aftermarket sleeve. The all-weather material is rated for rain, sun and snow, the finish is water-resistant, and a UV-resistant coating helps stop the black fabric from going grey.
Weighing 3.5 pounds, it is substantial without being awkward, and the form-fitted shape goes on and comes off easily even one-handed. That matters in cold weather more than it sounds.
What to check before you buy
This is a model-specific cover for the Traeger Pro 22 and Pro 575, sized at 35 by 23 by 42 inch. If you own a Pro 34 or a Texas grill, the BAC380 later in this list is the matched OEM option instead.
Owners consistently frame the OEM premium as insurance for grill longevity rather than a markup, and the multi-year reports back that reasoning.
Where it falls short
The only consistent complaint is cost, because aftermarket covers for the same grills cost a fraction of this. You are paying for the exact fit and for Traeger backing a part it designed for that specific cabinet.
There is a limit to what the form fit solves. A 35 inch cover on a grill sitting in a snow drift will still need the drawstring-style check, because the fit itself cannot stop accumulation on the top panel.
4. QuliMetal 600D Cover for Pit Boss Austin XL and 1100 Series
QuliMetal Grill Cover for Pit Boss Austin XL/1000/1100 Series
600D Oxford fabric
Waterproof and crack-proof
Ventilation ports for moisture control
62 by 24 by 47 inch
Pros
- Covers Pit Boss 1000 and 1100 series plus the Z Grill 1000D
- 600D Oxford rated waterproof UV-resistant and crack-proof
- Ventilation ports meaningfully reduce condensation and rust
- Elastic drawstring keeps the cover planted in wind
Cons
- Excludes PB1100PSC2 and the 65 inch Pro Series 1100 with side smoker
- Fit is model-specific so buyers must verify grill dimensions
Pit Boss 1000 and 1100 series grills have more size variants than any other family we covered, so a cover that names its exclusions clearly is worth more than one that vaguely claims to fit. This listing does the work: it lists the models it covers and the two it does not.
The 600D Oxford is rated waterproof, UV-resistant and crack-proof, with high-density stitching resisting tears and abrasion. At 62 by 24 by 47 inch it has the length to wrap past the hopper on the larger cabinets, and the adjustable elastic drawstring hem keeps wind from getting underneath.
Ventilation ports reduce moisture, rust and mildew, which is the same feature that made us pick the Recteq cover. More than 5200 reviews at 4.8 stars, with 86 percent five-star, is one of the strongest consistency records in the group.
What to check before you buy
Check the model number before anything else. The cover fits the Austin XL, Rancher XL 1000S, 1000D3, 1000SC, 1000SQ, 1100 Pro, PB1100PS1, Pro 1150, the 1000T4 Mahogany and the Z Grill 1000D, but it explicitly does not fit the PB1100PSC2 or the 65 inch Pro Series 1100 with side smoker.
The side smoker is the trap. A grill with a side smoker is physically a different shape and a shorter cover will sit over the wrong part.
Where it falls short
Fit confusion is the recurring negative theme in reviews, and it is not a fault in the cover. Owners who assumed a 1100-series grill was automatically covered discovered the exclusions after ordering.
The 600D Oxford used here is lighter than the 900D Oxford on our top pick, so on a grill in heavy snow country you may still want to clear accumulated weight off the top after a storm.
5. Pit Boss 5-Series Wood Pellet Vertical Smoker Cover
Pit Boss 5-Series Wood Pellet Vertical Smoker Cover, Black
OEM cover for the PBV5P1
Polyester with PVC backing
Drawstring closure
One year limited warranty
Pros
- OEM cover tailored specifically for the PBV5P1 vertical smoker
- Polyester with PVC backing protects against rain sun and snow
- Drawstring creates a secure fit in wind
- Easy to clean with water and mild detergent
Cons
- Fits only the 5-Series vertical smoker
- No ventilation features listed to manage condensation
Vertical smokers get skipped by most cover lists because their shape does not match a standard barrel grill. If you own the Pit Boss PBV5P1, this is the OEM cover cut to that cabinet, and a purpose-made fit beats a universal sleeve every time in wind.
The build is heavy-duty polyester with a PVC backing, which is what carries the water resistance through snow and rain, and the drawstring closure cinches the bottom so the cover cannot lift. It is also simple to hose off and air dry, which you will do at least once a season.
Just under 3900 reviews at 4.8 stars with 91 percent five-star is an unusually strong result for an accessory, and the review pattern centres on exact fit and durable weatherproofing rather than anything mixed.
What to check before you buy
This is a single-model cover for the Pit Boss 5-Series, listed as PBV5P1. Confirm your smoker model number before ordering, since Pit Boss has released several vertical smokers that look similar from a distance.
It comes with a one year limited manufacturer warranty from Dansons, which is a reasonable signal on an outdoor accessory.
Where it falls short
There are no ventilation features listed. On a vertical smoker with a chimney and a large hopper area, condensation has fewer escape routes, so wipe the smoker down and let it air out before covering it.
If your smoker is a different brand or a later vertical model, none of this applies and you will need a different cover entirely.
6. Traeger BAC380 Full-Length Cover for Pro 34 and Texas Grills
Traeger Grills BAC380 Full-Length Grill Cover Grill Accessory – Pro 34
Form-fitted OEM cover
Water-resistant construction
Sized for Pro 34 and Texas grills
49 by 22 by 39 inch
Pros
- Form-fitted for the Traeger Pro 34 and Texas grills
- All-weather material rated for rain sun and snow
- Water-resistant and easy to fit or remove
- 4.8 stars across more than 3000 reviews
Cons
- Carries a premium for what is a fitted cover
- Fits only the Traeger Pro 34 and Texas grill models
This is the matched OEM cover for the larger Traeger cabinets, and the 49 by 22 by 39 inch footprint is what you want on a grill with a wide cooking surface. Generic universal covers cut for the Pro 575 tend to sit short on this body, which is why wind gets in.
The material is heavy-duty and all-weather, built for rain, sun and snow, with a water-resistant construction and a form-fitted shape that goes on and off without a fight. It weighs 3 pounds, enough heft to stay put when you cinch it down.
More than 3000 reviews at 4.8 stars with 90 percent five-star shows the same consistent satisfaction we saw with the smaller Traeger cover, which is a good sign for Traeger accessory quality in general.
What to check before you buy
Confirm you own a Pro 34 or a Texas grill. The cover is cut for those bodies and will not fit a smaller Pro 575, which has its own matched cover earlier in this list.
Measure the grill including the hopper lid anyway, since Traeger cabinet dimensions have shifted slightly across production years.
Where it falls short
Buyers consistently call out cost as the only complaint, typically framing the premium as paying for Traeger build quality. The functional case for the OEM cover is fit, not fabric, and the material is comparable to good aftermarket sleeves.
Like the smaller OEM cover, it has no venting listed. Give the grill a day to air out in the sun before you pull this on, particularly after a wet week.
7. Arcedo Waterproof Cover for Pit Boss Sportsman 1100 and 1600
Arcedo Pellet Grill Cover Compatible with Pit Boss Sportsman 1100 and 1600
Waterproof vinyl coating over polyester
Solution-dyed fade-resistant fabric
Bottom fastening straps
62.5 by 25 by 47 inch
Pros
- Fits Pit Boss Sportsman 1100 and 1600 plus Pro Series models
- Waterproof vinyl coating over polyester keeps the grill dry year-round
- Solution-dyed fabric resists fading better than surface-dyed covers
- Bottom fastening straps hold the cover in high winds
Cons
- Buyers must confirm grill size and model number before purchase
- Not machine washable and requires hose or hand cleaning
The Sportsman 1100 and 1600 are big grills, and this cover is cut for them at 62.5 by 25 by 47 inch. Buyers who measured first report a clean fit with no loose fabric hanging off the corners, which is the difference between a cover that lasts and one that shreds.
Solution-dyed fabric is the quiet strength here. Because the colour runs through the thread rather than sitting on the surface, it resists fading in a way that surface-dyed polyester cannot, and UV fade is what turns a black cover grey and brittle after a few summers.
The waterproof vinyl coating over the polyester does the real weather work, and the bottom fastening straps tighten the hem to prevent slipping or blowing away in high winds. Around 2400 reviews at 4.7 stars, with 84 percent five-star, is a solid record for a brand-specific aftermarket cover.
What to check before you buy
Confirm your model number against the fit list, which covers the Sportsman 1100, Sportsman 1600, Pro Series 1600, Pro Series 1150, Savannah 1500 and the Mahogany 1000. That is a wide range of body sizes, so the size of the cabinet matters more than the brand name here.
Hook and loop fastening is used on this cover, which is easy to adjust but does not lock as firmly as a buckle or drawstring in sustained wind.
Where it falls short
Fit verification is the recurring friction in reviews. Buyers treat the listed model range as covering everything Pit Boss makes, when the 1100 and 1600 series contain cabinets that differ by several inches.
It is not machine washable, so cleaning means hosing it down or hand cleaning. Do that before you fold it away in spring, because a damp folded cover develops mildew.
8. Comnova 600D PU-Coated Cover for Pit Boss 820 and 850
Comnova Grill Cover for Pit Boss 820-850 – Z Grill 700 – Premium Wood Pellet Smoker Cover for Pitboss Waterproof & Heavy Duty, 600D Pellet BBQ Cover for Pit Boss 820 Deluxe, Pro 850 and Z Grill 700
600D Oxford with PU coating
PU is softer and more breathable than PVC
Adjustable Velcro straps
UV tested for aging
Pros
- Fits Pit Boss 820 and 850 models plus the Z Grill 700 series
- 600D Oxford with waterproof PU and UV-resistant coatings
- PU coating is softer and more breathable than PVC
- Adjustable Velcro straps on both sides for size flexibility
Cons
- Requires measuring the grill carefully before ordering
- Advises waiting 10 to 15 minutes for the smoker to cool before covering
The clearest PU-coated option in the group, and the coating matters more than it sounds. PU is softer and more breathable, so the cover releases moisture instead of trapping it against the barrel, which is why owners report better resistance to snow, rain and fading over time.
The fit map is broad, covering the Pit Boss 820 Deluxe, the Pro 850 series, 820D, 820FB, 820D3, 820SC, 820XL, 820PS1, Competition 850, Competition 820CS1, Sportsman 820 and the Z Grill 700 series, at 56 by 27 by 46 inch.
Adjustable Velcro straps on each side let the cover adapt between smoker sizes within that range, which is a useful hedge if you are not certain of your exact model. The fabric is UV tested against more than three years of accelerated ageing, and the quick-drying surface rinses clean and air dries fast.
What to check before you buy
Measure carefully, because this cover relies on adjustment rather than a form-fitted cut. If your grill measures near the edges of the listed dimensions, the Velcro will be doing all the work.
The instruction to wait 10 to 15 minutes after cooking before covering is sensible advice rather than a flaw. Putting a cover over a hot smoker can warp the material.
Where it falls short
Velcro straps collect grit and shed it over time, and they are the weakest link in a high-wind setup compared with a cinch cord or buckle.
Around 2440 reviews at 4.7 stars, the feedback clusters around fit verification being the main buyer-side concern. Check the model map before ordering rather than after.
9. Uniflasy 600D Cover for Recteq Flagship 1100 and 1600
Grill Cover for recteq Flagship 1100/1600, RT-700, RT-1250, RT-680
600D Oxford with PVC liner
Elastic drawstring hem
Reflective tape and carry handles
56 by 30 by 47 inch
Pros
- Covers the widest Recteq range in the group including RT-680 and RT-700
- 600D polyester Oxford fabric with an extra PVC liner resists tearing
- Drawstring hem plus side carry handles make it easy to secure and move
- Lowest entry cost among the covers we compared
Cons
- Reflective tape and handles are useful but the fit is generic to size rather than model-specific
- Looser cover shape may leave gaps compared with a form-fitted OEM cover
If you own a Recteq and want one cover that spans the Flagship range, this is the one. It fits the RT-680, RT-700, RT-1250, RT-1100 and RT-1600, at 56 by 30 by 47 inch, which covers almost every large Recteq body in production.
The build is 600D polyester Oxford with an extra PVC liner, described as tear-resistant as well as waterproof and fade-resistant. The adjustable elastic drawstring at the bottom handles wind, and the side carry handles make it practical to pull off and hang up in summer rather than leaving it in the corner folded damp.
Reflective tape makes the grill visible from 300 meters in the dark, which is a small feature that matters if you are covering a grill in a yard rather than beside a house. About 2200 reviews at 4.7 stars, with 83 percent five-star.
What to check before you buy
Measure your grill, because the sizing is by size rather than by model number. The extra width in this cover, 30 inch, is what allows it to cover the Flagship bodies as well as the smaller RT series.
If your grill is a Deck Boss or the RT-590, the QuliMetal cover earlier in this list is a tighter, vented alternative.
Where it falls short
The looser shape leaves gaps compared with a form-fitted OEM cover, and gaps are where snow and wind get in. The drawstring hem helps, but it cannot close a shape difference.
The single drawstring and hook and loop closure offer less adjustment than a buckle system, so this suits a sheltered yard better than an exposed one.
10. ZBXFCSH Heavy Duty 600D Cover for Z Grills 1000 Series
ZBXFCSH Heavy Duty Replacement Grill Cover Compatible with Z Grills 1000 Series 1000D/10002B Pellet Grill and Smoker
600D Oxford canvas with PVC lining
Cinch cord at the base
Form-fitted neutral black
Sizes for 700 600 and 1000 series
Pros
- Thick 600D Oxford canvas with a waterproof inner coating
- Cinch cord at the base keeps rain out and stops the cover blowing off
- Outlasts the thin factory cover that owners report fading and holing
- Also available in 700 600 450 and 550 series sizes
Cons
- Smallest review base in the group at 595 ratings
- Brand does not offer covers for other grill brands
Z Grills owners tend to start with the thin factory cover and discover two years later that it has faded and holed through. This one is the replacement people move to, and the 600D Oxford canvas with a PVC-lined interior is a genuine step up in thickness.
The PVC lining is the interesting part. It prevents tearing from the inside out, which is how fabric covers usually fail when wind works them against a shelf edge, and the cinch cord at the base keeps rain out while stopping the cover from lifting.
One owner reported buying a second cover after the first survived two winters in harsh New York weather, which is the durability evidence this category needs. The same line is available in 700, 600, 450 and 550 series sizes, so the brand covers most of the range.
What to check before you buy
This covers the Z Grills 1000 series, including the 1000D and 10002B pellet grill and smoker. Confirm the series number on your grill, because the 700 and 600 bodies are different covers.
Pick the version whose measurements match your grill within about an inch on length and width, since a stretched fit is the main way these covers fail.
Where it falls short
With 595 ratings, this has the smallest review base of the ten, so the durability picture rests on fewer owners than the others. The rating is still a solid 4.6 with 83 percent five-star.
The brand makes covers only for Z Grills models. If you later change grills, you are starting the search again rather than reusing this one.
Insulated Winter Blanket vs Standard Storage Cover
A storage cover and an insulated winter blanket solve completely different problems, and confusing the two is the most common mistake we saw in owner discussions. A storage cover keeps weather off a grill that is not being used. A blanket keeps heat in a grill that is cooking.
Insulated blankets are typically made from fire-resistant fiberglass and are sized around the chimney, with a cutout that lets the grill run underneath. The pitch behind them is better heat retention and lower pellet consumption during a cook, because the grill does not fight the cold air as hard to hold temperature.
Several owners on pellet grill forums take a different route, draping a welding blanket over the grill while it is in use and securing it with magnets. That approach works for a cook, but it is not a storage solution and it leaves nothing on the grill overnight.
Our read: buy a fitted storage cover for the winter months, and treat a blanket as an optional cooking accessory if you regularly grill below freezing.
Material and Denier Explained: 600D vs 1000D
Denier is simply the weight of the thread, and it is the fastest way to compare two covers on material quality. For pellet grill covers, three materials cover almost the whole market.
600D Oxford polyester is the standard and the value pick. It handles rain, wind and UV well, and it is the fabric used in five of the covers we reviewed. It will not crack in cold weather when the stitching is reinforced.
900D to 1000D Oxford is the heavy-duty tier. Noticeably thicker, better in heavy snow country, and more resistant to abrasion and tearing. This is what we recommend if your grill sits in an exposed yard.
Vinyl and PVC-coated covers shed water extremely well but stay stiff in cold temperatures and can crack after repeated freeze-thaw cycles. A PU coating is the softer, more breathable alternative and is what the Comnova cover uses.
One retailer page in our research described its cover as Grade 4 denier waterproof fabric, which is not a standard grading system and tells you very little. The number on the specification list is the one to compare.
Should a Grill Cover Be Waterproof?
Yes, but waterproof on the outside is only half the job. A fully waterproof cover with no vents traps condensation against the metal, so the best covers pair a water-resistant or waterproof shell with ventilation ports or a breathable coating that lets moisture escape.
This is why we ranked the vented covers highly even though the fabric denier was not the highest. A cover that dries out is worth more than a thicker cover that keeps your grill damp all winter.
Storing Your Pellet Grill Outdoors Year-Round by Climate
Snow belt: prioritize drawstring hems, vents and 900D or heavier fabric. After a storm, brush accumulated snow off the top so the weight does not stretch the seams overnight.
Pacific Northwest: the constant damp is the enemy, not cold. Covers with ventilation ports and a breathable PU coating work best here, and the fabric should be dried before being folded away in spring.
Humid Southeast: airflow inside the cover matters most. A Yoder YS1500 owner in a humid region put it simply: you will want to cover it. Combined with a yearly grease channel clean, a vented cover handles this climate well.
Windy plains: fastening method decides the outcome. Drawstrings and cinch cords hold far better than hook and loop closures, and a cover with reflective tape is easier to find after a night of high wind.
Owners on pellet grill forums repeatedly recommend covering year-round even in mild climates, framing it as a small effort that protects a significant purchase. If you take the cover off in summer, hang it on a wall or hook rather than folding it into a damp corner. Our winter layering guide covers the other end of that same seasonal routine for people who cook outdoors all year.
Winterizing Your Pellet Grill Beyond the Cover
The cover is the last step, not the first. A six-step routine before you cover a grill for the season handles the damage that happens underneath the fabric.
Burn off the grease channel. Run the grill hot with an empty grease pan until remaining grease burns away. Trapped grease holds moisture against steel all winter and is the main source of hopper-area corrosion.
Empty and wipe the hopper. Vacuum out pellet dust, because dust absorbs moisture and becomes a paste. Wipe the hopper and the inside of the lid with a dry cloth.
Clean the ash pan and grease buckets. Ash is hygroscopic, so it pulls water out of the air and holds it against the firebox. Empty it and leave the pan off the grill while it dries.
Check and tighten hardware. Freeze-thaw cycles loosen bolts and fittings. Tighten the wheel bolts, the hopper bolts and the leg bolts before the first freeze.
Dry the grill completely. This is the rule people break. Never cover a damp grill. Let it stand uncovered with airflow around it until every surface is dry to the touch.
Fit and secure the cover. Pull the hem down over the base, cinch the drawstring or buckle until there is no slack, and confirm the chimney and grease channel are covered.
If you find a cover already cracked, faded or holed when you pull it off in spring, that is the normal end of life for a lower-denier fabric after a few seasons of UV. Wiping it with a damp cloth extends its life; replacing it before it splits is cheaper than replacing the grill corners it no longer protects.
Frequently Asked Questions
Should you cover your grill in the winter?
Yes, if the grill stays outdoors, and only if the grill is completely dry first. A winter cover keeps rain, snow and UV off the metal and lets moisture escape through vents, which slows rust and corrosion. Let the grill cool, wipe it down and let it air out before pulling the cover on.
What is the most durable material for grill covers?
For most pellet grills, heavy-weight Oxford polyester is the most durable practical choice. 600D Oxford is the standard, 900D to 1000D is the heavy-duty tier for exposed yards, and vinyl or PVC coatings shed water well but can stiffen and crack through repeated freeze-thaw cycles.
What is the best weather-resistant grill cover?
The best weather-resistant cover combines a waterproof or water-resistant shell, reinforced stitching, a drawstring or buckle hem and ventilation ports. Fit matters just as much: a form-fitted model-specific cover with a cinched hem beats a loose universal sleeve in wind and snow.
Can I keep a pellet grill outside?
Yes. Pellet grills are built for outdoor use, and owners regularly keep them outside year-round. The cover handles the winter damage, but you also need to burn off the grease channel, empty the ash pan and hopper, and tighten bolts before the first freeze.
Should a grill cover be waterproof?
Waterproof is useful, but it is not enough on its own. A waterproof cover with no vents traps condensation against the metal, so look for ventilation ports or a breathable PU coating that lets moisture escape. Never cover a damp grill, because sealed-in moisture causes rust.
Do I need an insulated cover or a regular cover?
You need a regular fitted cover for winter storage. An insulated blanket made from fire-resistant fiberglass is a separate accessory that keeps heat in so you can cook in cold weather and use less fuel, rather than protecting a stored grill.
Final Verdict: Which Pellet Grill Cover to Buy in 2026
For most people, the SHINESTAR 900D cover is the best pellet grill cover for winter, because it combines the heaviest fabric, reinforced stitching, a drawstring hem and a zipper with the largest owner record of any cover we tested. Recteq owners should take the QuliMetal vented cover for the RT-590 and Deck Boss range, or the Uniflasy cover for the Flagship bodies.
Traeger owners have the easiest decision, since the BAC503 for the Pro 575 and Pro 22 and the BAC380 for the Pro 34 are exact-fit OEM covers rated 4.9 and 4.8 stars. Pit Boss 1000 and 1100 owners should use the QuliMetal Austin XL cover and check the model exclusions, while vertical smoker owners need the Pit Boss 5-Series cover, and Z Grills owners need the ZBXFCSH cover for the 1000 series.
Whatever you choose, dry the grill before you cover it and cinch the hem tight. A cover only protects a dry grill, and the same rule applies whether you are storing a grill for the season or just for a rainy week. Our cast iron grill pan picks are worth a look for anyone who wants to keep cooking through the cold months instead of shutting down.
