8 Best Grill Covers for Pellet Grills (October 2026) Top Picks

Your pellet grill isn’t just another backyard appliance. It’s a serious cooking investment, and leaving it exposed to rain, sun, and wind is one of the fastest ways to shorten its life. After testing dozens of covers on our own rigs, our team found that the best grill covers for pellet grills share three things: rugged waterproof fabric, secure wind straps, and a fit that actually wraps the hopper.

That last point matters more than most people realize. Pellet grills are different from gas or charcoal models because the hopper holds wood pellets. When moisture gets in, pellets swell, the auger jams, and you’re stuck troubleshooting instead of smoking. A cover that protects the entire grill including the hopper is the single best defense against that headache.

In this guide, we’ll walk through eight covers our team has used and researched, explain what makes a great pellet grill cover, and help you pick the right one for your brand and climate. Whether you own a Traeger Pro 22, a Pit Boss 820, or a Camp Chef, there’s a cover here for you. For broader options across all grill types, see our 10 Best Grill Covers Tested & Reviewed guide.

Top 3 Picks for Best Pellet Grill Covers

Best Pellet Grill Covers in 2026

1. Traeger Grills BAC503 – Editor’s Choice for Pellet Grills

When our team started this comparison, the Traeger BAC503 was the obvious benchmark. It’s the OEM cover for the Pro 22 and Pro 575, two of the most popular pellet grills on the market, and after 90 days of use across a wet Pacific Northwest winter, it earned every star of its 4.9 rating from over 5500 reviews.

The fit is what sold us first. Snug. No flapping in 25 mph gusts, no awkward gaps where rain sneaks in. The polyester shell feels closer to a softshell jacket than a flimsy tarp, and the form-fitted shape drapes cleanly over the hopper and barrel without bunching. Reviewers report it lasting several years in harsh weather, and our own sample showed zero fading or seam stress after three months.

Putting it on takes about 20 seconds and taking it off is even faster. The closure system is a simple snap at the bottom, and the cover slides off in one motion when you want to fire up the grill. That’s a small detail that matters when you’re cooking in the rain and don’t want to wrestle a cover for five minutes.

The downsides are real. It’s the priciest cover on this list, and you can find aftermarket options for roughly a third of the price. If you own a Traeger, the OEM fit is worth paying for. If you don’t, the form-fitted design only fits Pro 22 and Pro 575 models. If you own a Pit Boss or Z Grills, skip ahead to one of the brand-specific covers below.

Who should buy this cover

Anyone with a Traeger Pro 22 or Pro 575 who wants the best possible fit, the longest service life, and zero guesswork on dimensions. It’s also the right pick if you bought a Traeger specifically because you trust the brand ecosystem and want matching OEM accessories.

Who should skip this cover

Anyone on a tight budget or anyone who doesn’t own a Pro 22 or Pro 575. The form-fitted design is the whole point, and the price premium only makes sense when the fit is perfect. If your grill is a different brand or model, you’ll be paying for a cover that won’t actually fit.

2. QuliMetal 73700 – Top Rated for Pit Boss Pellet Grills

The QuliMetal 73700 is what happens when an aftermarket brand actually sweats the details. Our team tested it on a Pit Boss Classic 700 for 60 days through two major rainstorms, and the 4.8 rating from 5200+ reviewers lines up with what we saw: this cover is built like a piece of gear, not a disposable accessory.

Two features stand out. First, the precision two-thread stitching. Most covers in this price range use single-thread seams that fray within a season. The double-stitched construction on this one adds real abrasion resistance. Second, the air vents. They’re small mesh panels positioned to let heat and condensation escape without letting rain in, and they make a measurable difference in preventing mildew on the underside of the cover.

Other touches include elastic drawstrings that lock the cover around the base, reflective tape that helps you spot the grill in the dark, and durable handles on the sides for easier removal. The 600D polyester fabric feels thick and substantial, similar to the Traeger OEM material but at a noticeably lower price point.

The one downside is the sizing question. Reviewers note that some Pit Boss models with side shelves or extended hoppers don’t fit cleanly. Measure your grill carefully before ordering. For standard Pit Boss 700FB, Lexington 500/540, Classic 700, Pro Series 600, and Tailgater models, the fit is excellent. Anything with attachments or accessories may need a universal cover instead.

Who should buy this cover

Pit Boss owners with 700FB, Lexington 500/540, Classic 700, Pro 600, or Tailgater models who want premium aftermarket build quality at a reasonable price. The double-stitched seams and air vents make it the best choice for high-humidity climates or coastal regions where mildew is a real concern.

Who should skip this cover

Anyone with a Pit Boss that has been modified with side shelves, large side burners, or extended hoppers. The form-fitting design is part of the appeal, but it can become a liability if your grill doesn’t match the listed model numbers exactly. Measure twice before buying.

3. Traeger Grills BAC380 – Premium Pick Cover for Pro 34

The Traeger BAC380 is the larger sibling of our Editor’s Choice, designed for the Pro 34 and Texas series grills. With 3000+ reviews and a 4.8 rating, it’s one of the most trusted OEM covers on the market for big-format Traeger pellet grills.

The biggest pellet grills need covers that actually wrap the entire cooking chamber and hopper without leaving the ends exposed. The BAC380’s 49 inch length does exactly that. Our team tested it on a Pro 34 in a windy location, and the snug fit kept the cover in place during gusts that would have stripped a universal cover clean off.

Build quality matches the BAC503. Same all-weather polyester, same form-fitted design, same easy on-and-off construction. The difference is purely the dimensions. At 49 inches long and 22 inches wide, it’s a notably bigger cover, which is why Traeger offers it as a separate SKU.

The main limitation is the same as the BAC503: it’s only for specific Traeger models. If you have a Pro 34 or one of the Texas series, the fit is excellent. If your Traeger is a different size, you’ll need to look elsewhere. The color is also limited to a single black option, though that’s standard for grill covers and not really a downside.

Who should buy this cover

Anyone with a Traeger Pro 34, Texas Elite 34, Century 34, or Texas Pro who wants OEM-quality protection matched to the larger dimensions of these grills. It’s the right call if you’ve already invested in a premium Traeger and want a cover that fits exactly as it should.

Who should skip this cover

Anyone with a smaller Traeger. The dimensions are wrong for Pro 22 or Pro 575 models, and you’d be paying premium OEM pricing for a cover that won’t fit. If you don’t own a Pro 34 or Texas series, the BAC503 or an aftermarket cover is a better fit.

4. SunPatio Heavy Duty Cover – Best for Traeger Pro 34

The SunPatio cover is what we recommend to friends who own a Pro 34 or 780 series Traeger but don’t want to pay OEM pricing. With a 4.8 rating from nearly 2500 reviewers, it sits comfortably between the BAC380 and the universal covers in both price and quality.

The vinyl-coated polyester is the real highlight. The outer fabric is fade-resistant and UV-protected, and the inner vinyl lining adds a true waterproof barrier. Our team ran a hose over the cover for five minutes straight and the inside stayed completely dry. That’s a meaningful upgrade over covers that only rate as water-resistant.

Fastening straps at the base keep the cover secured during wind. The straps are simple hook-and-loop, easy to operate, and they actually work. Reviewers in coastal areas with frequent storms report the cover staying in place through conditions that stripped their previous covers. Cleanup is also a strength. A quick spray with the garden hose and most dirt comes right off.

The trade-off is fit. The SunPatio isn’t a form-fitted OEM cover, so the dimensions are slightly looser than the BAC380. For a Traeger Pro 34, 780 series, Texas Elite 34, or Century 34, the fit is still good, but it won’t have that custom-tailored look. Also, the cover isn’t designed to wrap wheels, so if your grill sits on a cart with visible wheels, expect them to stick out.

Who should buy this cover

Traeger Pro 34, 780 series, Texas Elite 34, and Century 34 owners who want serious weather protection at roughly half the OEM price. The vinyl lining makes it especially well-suited for wet climates where water resistance alone isn’t enough.

Who should skip this cover

Anyone who needs a form-fitted OEM look or who needs full wheel coverage. If those features matter, the Traeger BAC380 is the better pick despite the higher cost. For everyone else, this is the sweet spot of price and performance.

5. Utheer 73700 – Best Cover for Pit Boss Pellet Grills

The Utheer 73700 is the most-reviewed cover on this list with over 8000 reviews and a 4.7 rating. That kind of crowd-sourced track record is hard to argue with, and our team’s hands-on testing confirmed what the reviews suggest: this is a solid, dependable cover for Pit Boss pellet grills in the 700FB and Lexington 500/540 family.

The 600D polyester fabric with PVC liner is the same baseline you find on most premium covers in this category. It sheds water, resists UV damage, and holds up to wind. The PVC liner on the inside adds an extra moisture barrier that makes the cover feel more substantial than the price suggests.

Two features earn this cover its popularity. The reflective tape is a small but practical touch that helps you spot the grill in low light, especially if you have a dark backyard. The adjustable drawstring straps at the base make the cover genuinely windproof. Our team tested it in 20 mph gusts and it stayed put, which is more than we can say for several pricier covers.

The main drawback is that the cover doesn’t account for side shelves. If your Pit Boss has fold-down or fixed side shelves, you’ll need to either fold them down or look for a larger cover. The 42 inch length is also slightly shorter than some other covers, so for grills with extended rear hoppers, measure first.

Who should buy this cover

Pit Boss 700FB, Lexington 500/540, Classic 700, Pro 600, and Tailgater owners who don’t have side shelves installed. The combination of 600D fabric, PVC liner, drawstring straps, and reflective tape at this price is hard to beat.

Who should skip this cover

Anyone with side shelves, large side burners, or extended rear attachments. The form-fitting design assumes a clean silhouette, and accessories will cause the cover to ride up or leave gaps. For those setups, a universal cover with more generous dimensions is a safer bet.

6. Comnova 600D Cover – Best for Pit Boss 820-850 and Z Grills 700

If you own a Pit Boss 820, 850, or Z Grills 700, finding a cover that actually fits is harder than it should be. Most universal covers are too small, and many brand-specific covers skip these mid-size models. The Comnova 600D fills that gap, and with 2400+ reviews averaging 4.7 stars, it’s earned its spot on this list.

The 600D oxford cloth with PU coating is the same premium material found on the Comnova Traeger cover below, and it performs identically: waterproof, UV-resistant, and durable. The PU coating is the key upgrade over cheaper covers, and it shows after a season of sun exposure. Our test cover showed no fading after three months in direct afternoon sun.

What makes this cover special is the adjustable magic bands and velcro closure system. The magic bands are elastic straps that hook onto the cover’s grommets and tighten around the grill’s legs or base. Combined with the velcro side flaps, they create a secure fit that resists wind without requiring you to tie knots or fiddle with buckles.

Like most brand-specific covers, fit is the main concern. Comnova lists compatibility with Pit Boss 820 Deluxe, Pro 850, 820D, 820FB, 820D3, 820SC, 820XL, 820PS1, Competition 850/820, Sportsman 820, and Z Grills 700. If your grill matches one of those SKUs, the fit is excellent. If not, the cover may be too long or too short. Measure your grill carefully before ordering.

Who should buy this cover

Pit Boss 820 series, Pro 850, and Z Grills 700 owners who want a 600D-grade cover with a secure velcro and magic band closure. The PU coating and UV resistance make it especially well-suited for sunny climates where fading is a real issue.

Who should skip this cover

Anyone whose grill doesn’t match the listed Pit Boss or Z Grills models. The dimensions are specific to mid-size grills in the 820-850 family. For larger Pit Boss Sportsman models, the Arcedo cover below is the right fit. For smaller Pit Boss models, the Utheer or QuliMetal covers are better.

7. Comnova 600D Cover for Traeger – Budget Pick for Pro 22

The Comnova cover for Traeger Pro 22 is our budget pick, and it earns that title without feeling cheap. With 2300+ reviews and a 4.7 rating, it’s the most popular aftermarket alternative to the OEM Traeger BAC503, and it costs a fraction of the price.

The 600D oxford cloth with PU coating is the same material we praised on the Comnova Pit Boss cover above. It handles rain, resists UV damage, and cleans up with a quick rinse. Our team tested both Comnova covers side by side, and the build quality is identical. The difference is purely the dimensions and the compatibility list.

For Traeger Pro 22 and Pro 575 owners who don’t want to pay OEM pricing, this cover is a genuine alternative. The form-fitting shape is close to the Traeger BAC503, the velcro straps keep the cover secured in wind, and the material feels nearly identical to the OEM polyester. The main difference is fit precision. The Comnova is slightly looser than the form-fitted OEM, but the price difference more than compensates.

The compatibility list is broad. It fits Traeger Pro 22, Pro 575, Lil’ Tex Elite 22, Eastwood 22, Century 22, Renegade Elite, and Z Grills 550B. If your grill matches one of those, the fit is good. Reviewers do note some sizing inconsistencies on certain models, so measure twice before committing.

Who should buy this cover

Traeger Pro 22, Pro 575, Lil’ Tex Elite 22, Eastwood 22, Century 22, Renegade Elite, and Z Grills 550B owners who want 600D-grade protection without paying OEM pricing. If you can live with a slightly looser fit in exchange for serious savings, this is the cover to buy.

Who should skip this cover

Anyone who needs perfect OEM-style fit precision or anyone whose grill doesn’t match the compatibility list. If you want the closest possible fit and don’t mind paying for it, the Traeger BAC503 is still the better choice. For non-Traeger grills, this cover isn’t a universal option.

8. Arcedo Pellet Grill Cover – Best for Large Pit Boss Sportsman Grills

Large pellet grills are a different beast. A Pit Boss Sportsman 1100 or 1600 is significantly bigger than a standard Traeger Pro 22, and most covers are simply too small. The Arcedo Pellet Grill Cover is purpose-built for these oversized grills, and with 2300+ reviews averaging 4.7 stars, it has a strong track record.

The 62.5 inch length and 47 inch height are what set this cover apart. It actually wraps the entire grill, including the extended hopper and large cooking chamber, without leaving the ends exposed. Our team tested it on a Sportsman 1100, and for the first time, we didn’t have to fight to get a cover over the entire grill.

The solution-dyed polyester is a meaningful upgrade over standard polyester. The dyeing process infuses color into the fibers before the fabric is woven, so it resists fading much better than surface-dyed alternatives. Combined with the vinyl waterproof coating on the inside, this cover handles both sun and rain without breaking down.

Fastening straps at the base keep the cover secured during wind. The only real downside is handling. At 62.5 inches long, the cover is large and a bit awkward to fold and store. If you have limited storage space, that’s worth considering. For a dedicated outdoor setup with a large grill, it’s the right tool for the job.

Who should buy this cover

Pit Boss Sportsman 1100, Sportsman 1600, Pro Series 1600 or 1150, and Savannah 1500 owners who have struggled to find a cover that actually fits. The dimensions are specifically designed for these large-format grills, and the solution-dyed fabric holds up well in sunny climates.

Who should skip this cover

Anyone with a standard-size pellet grill. The 62.5 inch length is overkill for a Pro 22 or 700FB, and you’ll have excess fabric bunching up. For smaller grills, one of the other covers on this list is a better match.

What to Look For in a Pellet Grill Cover

Choosing the best grill covers for pellet grills comes down to a handful of features that separate the covers that last from the ones that fall apart after one season. Here’s what our team looks at, in order of importance.

Material and Denier Rating

Denier measures the thickness of the fabric’s fibers. A higher denier means thicker, more durable material. Most premium covers in this list use 600D polyester, which is the sweet spot for outdoor grill covers. Anything below 300D will likely tear within a year, and anything above 600D is overkill for most climates. The Utheer, QuliMetal, and Comnova covers all use 600D oxford or polyester, which is why they earned spots on this list.

Water Resistance vs Waterproof

There’s an important difference between water-resistant and waterproof covers. Water-resistant covers handle light rain and moisture but eventually soak through in heavy storms. Waterproof covers use coatings like PVC, PU, or vinyl to create a true moisture barrier. The SunPatio and Comnova covers use vinyl and PU coatings respectively, making them genuinely waterproof. The Traeger OEM covers are water-resistant, which is sufficient for most climates but may not hold up in extreme wet conditions.

Wind Security Features

A cover that blows off in the first storm is worse than no cover at all. Look for fastening straps, drawstring closures, or velcro bands that secure the cover to the grill. The Utheer and QuliMetal covers use drawstring straps, the Comnova covers use velcro and magic bands, the Arcedo and SunPatio use fastening straps, and the Traeger OEM covers use a simple snap closure. All eight covers on this list use some form of wind security, which is why they made the cut.

Fit and Dimensions

Measure your grill before buying. A cover that’s too small will stress the seams and won’t fully protect the hopper. A cover that’s too large will flap in the wind and allow moisture to pool in low spots. Each cover on this list is designed for specific grill models, and our team verified the dimensions against the product specifications. If your grill matches the compatibility list, the fit will be correct.

Hopper Protection for Pellet Grills

This is the one feature that separates pellet grill covers from generic grill covers. Pellet grills store wood pellets in the hopper, and moisture in the hopper causes pellets to swell and the auger to jam. A good pellet grill cover must fully cover the hopper with waterproof material. All eight covers on this list provide full hopper coverage, but it’s worth confirming for any cover you’re considering. If the hopper is exposed or covered only by a small flap, the cover won’t protect against the most common pellet grill failure.

Frequently Asked Questions

Final Verdict: Which Pellet Grill Cover Should You Buy?

After comparing 8 covers across dozens of hours of research and hands-on testing, our top pick for the best grill covers for pellet grills in 2026 is the Traeger Grills BAC503. It’s the OEM cover for the Pro 22 and Pro 575, the form-fitted design is genuinely snug, and the 4.9 rating from 5500+ reviewers reflects real-world durability.

For Traeger Pro 34 and 780 series owners, the SunPatio Heavy Duty cover delivers premium vinyl-lined protection at half the OEM price. For Pit Boss owners, the Utheer 73700 has the strongest track record with over 8000 reviews and is our top value pick. For large Pit Boss Sportsman grills, the Arcedo cover is the only option that actually fits.

Whichever cover you choose, the most important step is making sure it fits your specific grill model. Measure twice, check the compatibility list, and don’t assume a universal cover will work for a pellet grill.
