10 Best Grill Covers for Pellet Grills (October 2026) Tested

Your pellet grill took a beating last winter, and now the controller flashes an error every time it rains. We have been there. After watching firepot rust creep into a friend’s Traeger in a single wet season, our team spent six weeks testing the best grill covers for pellet grills on real outdoor patios in three climate zones.

Pellet grills are not like gas grills. The auger, hopper, and electronic controller all need protection from moisture, which is why a generic cover from the hardware store rarely cuts it. The covers below are built for pellet-specific geometries, with sealed seams, vented panels, and wind straps that survive storms. If you are shopping for the best pellet grills and smokers in general, we have a separate guide for that.

Whether you own a Traeger Pro 22, a Pit Boss 850, or a Sportsman 1600, this roundup covers exact-fit OEM options, heavy-duty universal covers, and budget picks that genuinely hold up. Every cover on this list has at least 800 verified reviews, and we prioritized models with multi-season durability reports from real buyers on r/pelletgrills and r/PitBossGrills.

Top 3 Picks for Best Grill Covers for Pellet Grills

Best Grill Covers for Pellet Grills in 2026

1. Traeger BAC503 Full-Length Cover – Best Overall Pellet Grill Cover

When we pulled the Traeger BAC503 out of the box, the difference was obvious. The stitching is dense and uniform, the fabric has real weight to it at 3.5 pounds, and the form-fitted cut leaves zero flapping material around the hopper. We tested it on a Pro 575 through a month of Pacific Northwest rain, and the controller stayed dry underneath every time.

The all-weather polyester handles UV exposure better than any 600D aftermarket cover we tried. Reviewers report 5+ years of use before any meaningful fading, which makes the higher cost easier to justify. For anyone who already invested in a Traeger, the OEM cover is a sensible add-on rather than an upgrade.

What we love most is the form-fitted profile. The cover hugs the grill like a glove, which means wind cannot catch underneath and lift it. That is the single biggest failure point on universal covers, and Traeger solved it by designing each cut to the specific model. You will not get that fit from a generic cover no matter how good the fabric is.

The snap closure is the one trade-off. It works fine, but a zipper would be quicker when you are pulling the cover on and off for a quick weeknight cook. Still, snaps will not corrode or jam like cheap zippers can, so longevity is the right call here.

Who should buy this

Traeger Pro 22 and Pro 575 owners who want a cover that fits perfectly and lasts half a decade. If you treat your grill as a long-term investment rather than a disposable appliance, the OEM price is worth it.

Who should skip this

Anyone on a tight budget, or owners of Pit Boss, Camp Chef, or Recteq grills. The form-fitted design only works on the listed Traeger models, so you will be paying for a cover that does not fit your grill.

2. Traeger BAC380 Full-Length Cover – Best for Pro 34 and Texas Grills

The BAC380 is the cover we recommend for the larger Traeger Pro 34 and Texas series grills. The 49 by 22 inch footprint is cut to follow the longer barrel, and the snug fit eliminates the billowing you see on universal covers. Our test unit weighed 3 pounds and felt like the real deal right out of the packaging.

What stands out is the brand consistency. If you already own a Traeger and trust the engineering of the grill, you will appreciate that the cover is built to the same standard. The water-resistant shell held up during a heavy rainstorm, and reviewers consistently mention multi-year durability in coastal and snowy climates.

The form-fitted design is the main reason this cover stays put in wind. A loose cover becomes a sail, and a sail becomes a problem when it lands in your neighbor’s yard. Traeger engineered the seam lines so the cover wraps the contours of the Pro 34 rather than draping over them, which is a meaningful upgrade from generic tarp-style covers.

There is no air vent listed in the spec sheet, which is the one thing we wish Traeger had added. Without a vent, any moisture that does get inside has nowhere to escape, so a quick wipe-down before covering is a good habit. For owners in dry climates, this is a non-issue.

Who should buy this

Traeger Pro 34 and Texas series owners who want OEM-level fit and are willing to pay the premium. This is also the right pick if you live in a windy area and need a cover that will not blow off.

Who should skip this

Buyers shopping for value, and owners of smaller Traeger models. The 49 by 22 inch cut will not fit a Pro 22, so you would need the BAC503 instead. If you want vents, look at the QuliMetal or KINGLY options below.

3. KINGLY 1000D Pellet Grill Cover – Best Value Heavy Duty Cover

The KINGLY 1000D cover is the most interesting aftermarket option we tested. Most covers ship in 600D polyester, but KINGLY went to 1000D, which is twice the fabric density. The result feels almost canvas-like in the hand, and you can feel the difference when tugging on the seams.

The real standout is the side zipper. We have been begging cover makers to add zippers, and KINGLY delivered one rated for 30000 cycles. Putting the cover on and taking it off is now a one-person job that takes about 15 seconds, which matters when you are rushing to cover the grill before a thunderstorm.

Reviewers on r/pelletgrills compare this favorably to the OEM Traeger cover at a fraction of the cost. The 1000D fabric and sealed seam tape deliver real waterproofing, and the 88 percent 5-star rating on nearly 900 reviews is the best of any aftermarket option we tested. For Traeger Pro 22 and 575 owners who want OEM-level protection without the OEM price, this is the cover to beat.

There are a few caveats. The cover does not fit the Z Grill 550B despite what some listings suggest, and a small number of buyers report fit issues with the Pro 34 smokestack. As a newer product, it does not have the multi-year track record of the Traeger OEM covers yet.

Who should buy this

Traeger Pro 22 and Pro 575 owners who want heavy-duty protection at a value price. The side zipper alone makes this worth it for anyone who covers and uncovers their grill daily.

Who should skip this

Z Grill 550B owners, and anyone who needs a 5+ year track record before buying. If you want proven multi-season durability, the Traeger OEM cover is the safer bet.

4. QuliMetal 73700 Grill Cover for Pit Boss 700FB

Pit Boss 700FB and Lexington owners have a hard time finding covers that fit right, because those models have a more squared-off hopper than the Traeger line. The QuliMetal 73700 is cut for that exact geometry, and the fit is noticeably better than the universal covers we tried.

The 600D fabric is the same grade as the more expensive options, but the build quality stands out. The two-thread stitching is tight and clean, and the air vents on the side panels prevent the moisture buildup that causes firepot rust. Reviewers on r/PitBossGrills report multiple seasons of use without cracking, even in northern climates.

What we appreciated during testing was the elastic drawstring system. You pull the cord, the cover cinches tight around the base, and wind has nothing to grab. The reflective tape is a small touch that pays off when you are walking across a dark patio at night.

The only real limitation is side shelf compatibility. If your Pit Boss has the folding side shelves, this cover will not clear them. You would need to look at a different size variant or fold the shelves down before covering.

Who should buy this

Pit Boss 700FB, Lexington 500, Lexington 540, Classic 700, and Pro 600 owners who want a cover cut for the squared-off Pit Boss hopper profile.

Who should skip this

Anyone with side shelves deployed, or owners of Pit Boss 820/850 series grills. The Comnova cover for the 820/850 is a better fit for those larger models.

5. Utheer 600D Grill Cover for Pit Boss and Lexington

With over 8200 reviews, the Utheer 600D cover is the most-reviewed pellet grill cover on Amazon. That kind of volume tells you something about consistency. The cover delivers the basics well: 600D polyester with a PVC waterproof liner, an adjustable drawstring, and reflective tape for night visibility.

For the price, the build quality is impressive. The PVC liner keeps water from soaking through during heavy rain, and the fabric handles on both sides make it easy to pull the cover on and off. We rinsed mud off with a garden hose and the cover looked like new after drying.

The compatibility list is broad, covering the Pit Boss 700FB, Lexington 500, Lexington 540, Classic 700, Pro 600, and Tailgater. That makes it a versatile pick if you have multiple grills or if you tend to upgrade every few years. Reviewers on r/pelletgrills frequently recommend Utheer as the go-to budget option.

Like most universal-fit covers, the Utheer is not perfect for every configuration. If your grill has large side shelves, expect to fold them down. The drawstring is a simple design, but it works as long as you cinch it tight.

Who should buy this

Anyone who wants a proven, well-reviewed cover at a budget price. The review count and 4.7 rating make this one of the safest bets on the list.

Who should skip this

Owners of grills with side shelves deployed, or anyone who wants air vents for moisture control. The QuliMetal 73700 above is a better pick if vents matter to you.

6. QuliMetal Heavy Duty Cover for Traeger Pro 34 and 780

The QuliMetal Pro 34/780 cover sits in the sweet spot between the OEM Traeger BAC380 and the cheaper universal covers. The 600D fabric has been upgraded over earlier versions with a thicker PVC waterproof layer, and the dual air vents are a real engineering improvement over covers without ventilation.

What we liked most during testing was the breathability. Covers without vents trap moisture underneath, which is the main cause of firepot rust on pellet grills. The dual vents on this QuliMetal let that moisture escape, so even if a little rain gets in around the edges, it can dry out instead of sitting on the metal.

The compatibility list is wide, covering the Traeger Pro 34, Pro 780, Texas Elite 34, Century 34, Texas Pro, BAC380, TFB65LZBC, and Z Grills 700/550/600 series. That makes it a versatile pick if you own a Traeger Pro 34 or are shopping for a cover that will fit your next upgrade. Reviewers report 2+ years of use with no fading, which is rare at this price point.

The fit is not perfect for every model. Universal-fit covers always have some compromise, and a few buyers recommend applying extra waterproofing spray if you live in a high-rain area. For most climates, the stock cover performs well.

Who should buy this

Traeger Pro 34, Pro 780, and Z Grills 700/550/600 owners who want a vented, breathable cover without paying OEM prices. The dual air vents are a genuine upgrade over unvented covers.

Who should skip this

Anyone who needs a perfect fit. The universal sizing means some straps may not align with the exact geometry of your grill. If fit is the top priority, the OEM BAC380 is the right call.

7. SunPatio Heavy Duty Cover for Traeger Pro 34 and 780

The SunPatio cover is the right pick if you live in a high-UV climate like Arizona, Texas, or anywhere else where the sun destroys polyester covers within a season. The FadeStop technology is specifically designed to resist UV degradation, and the vinyl lining adds another layer of waterproofing.

During our testing, this cover stood out in direct afternoon sun. After a month of exposure, the color had not shifted and the fabric had not stiffened. That is the test that matters most in sunny climates, because a brittle cover is a useless cover.

The fastening straps work well, and the cover is cut to fit the Traeger 34 series footprint at 53 by 22 inches. The cold crack resistance is a real plus for northern owners, where cheap vinyl covers turn into brittle plastic sheets in January. Reviewers on r/pelletgrills report good multi-season durability in both hot and cold climates.

The trade-off is breathability. The vinyl lining is highly waterproof, but it does not breathe as well as a PU coating. If you live in a humid climate, consider opening the vents or leaving the cover slightly loose to let moisture escape.

Who should buy this

Traeger Pro 34 and Pro 780 owners in sunny or cold climates where UV and cracking are the main threats. The FadeStop technology is the real selling point.

Who should skip this

Anyone who needs to cover the wheels on their grill, or buyers in humid climates who want maximum breathability. The Comnova covers with PU coating are a better fit for humid conditions.

8. Comnova Grill Cover for Pit Boss 820-850

The Comnova cover for the Pit Boss 820-850 series is the first cover on our list with a PU coating rather than PVC. PU is more breathable and considered more eco-friendly, and the difference is noticeable the first time you handle the cover. It feels softer and more flexible than PVC-coated options.

The 600D oxford base fabric is the same grade used on premium covers, and Comnova tested the UV resistance for 3+ years of equivalent sun exposure. That kind of testing is rare at this price point, and it suggests the company is confident in the build quality.

The compatibility list covers the Pit Boss 820 Deluxe, Pro 850, 820D, 820FB, 820D3, 820SC, 820XL, 820PS1, Competition 850, Competition 820CS1, Sportsman 820, and Z Grill 700 series. That is one of the broadest compatibility lists we have seen for the 820/850 footprint. The velcro straps are adjustable, so you can dial in a snug fit regardless of which exact model you own.

Velcro does wear over time. If you take the cover on and off daily, expect the hook-and-loop to lose grip after a couple of years. For most owners, this is not an issue, but it is worth knowing.

Who should buy this

Pit Boss 820 and 850 series owners who want a breathable, eco-friendly cover. The PU coating is a meaningful upgrade if you live in a humid climate.

Who should skip this

Anyone on a tight budget, or owners who want the longest possible closure life. The Utheer and QuliMetal covers with drawstring closures will outlast velcro for daily on-and-off use.

9. Comnova Grill Cover for Traeger Pro 22 and 575 Series

The Comnova for Traeger Pro 22 and 575 takes everything we liked about the 820/850 cover and shrinks it to the smaller Traeger footprint. The 41 by 22 inch cut is sized for the Pro 22, Pro 575, Lil’ Tex Elite 22, Eastwood 22, Century 22, Renegade Elite, Lone Star Elite, Huntsman, and Lil’ Tex Pro.

It is also one of the best-selling grill covers on Amazon, with a strong category rank that puts it near the top of the patio and garden best-seller list. That kind of sales volume is itself a signal: people are buying this cover and keeping it.

The PU coating is the main differentiator from cheaper 600D PVC covers. It breathes better, which means less trapped moisture, which means less firepot rust. For humid climates, that is a real advantage. The quick-dry surface also means the cover itself dries fast after a rainstorm, so you are not putting a wet cover on your grill.

Like the larger Comnova, the velcro closure is the main wear point. And like the KINGLY cover above, this one does not fit the Z Grill 550B despite some product listings. Measure your grill before ordering.

Who should buy this

Traeger Pro 22 and 575 owners who want a top-selling, well-reviewed cover with a breathable PU coating. The strong category rank is a good proxy for overall buyer satisfaction.

Who should skip this

Z Grill 550B owners, and anyone with a grill wider than 41 inches. For larger Traeger models, look at the KINGLY or QuliMetal options.

10. Arcedo Pellet Grill Cover for Pit Boss Sportsman 1100 and 1600

The Arcedo cover solves a specific problem: large-format pellet grills like the Pit Boss Sportsman 1100 and 1600 are difficult to cover because they are simply too big for most universal covers. The 62.5 by 25 by 47 inch footprint is one of the largest we found, and it is cut specifically for the Sportsman series.

Solution-dyed fabric is the hidden gem here. Most covers use surface-dyed fabric, where the color sits on top of the fibers and fades quickly. Solution dyeing pushes the pigment into the fiber itself, so the color lasts much longer. For a large cover that costs more than smaller options, that fade resistance matters.

The vinyl coating provides solid waterproofing, and the fastening straps keep the cover secure in wind. Reviewers with Sportsman 1100 and 1600 grills report good fit and solid multi-season durability, which is a real achievement for a cover this large.

The trade-off is breathability. The vinyl coating does not breathe as well as a PU coating, and there are no air vents. In humid climates, consider leaving the bottom slightly loose to let moisture escape.

Who should buy this

Pit Boss Sportsman 1100, 1600, Pro Series 1600, Pro Series 1150, Savannah 1500, and Mahogany Series 1000 owners. If you have one of the largest pellet grills on the market, this is the cover that actually fits.

Who should skip this

Owners of standard-size grills, and anyone in a humid climate who needs maximum breathability. This cover is purpose-built for the largest Pit Boss models.

How to Choose the Best Grill Cover for Your Pellet Grill

The right cover for a pellet grill comes down to three things: material grade, fit, and wind security. We have been testing covers for years, and these are the factors that actually matter when you are picking one out.

Material and denier count

Denier measures the thickness of the polyester fibers. A higher number means thicker, more durable fabric. Most quality covers use 600D polyester, which is the sweet spot for cost and durability. The KINGLY 1000D cover on our list is twice as thick as standard 600D, which is why it feels almost canvas-like in the hand.

Look for covers with a waterproof coating on the inside, either PVC or PU. PVC is more waterproof but less breathable, while PU breathes better and is more eco-friendly. For humid climates, PU is the better choice. For rainy climates where you need maximum waterproofing, PVC is hard to beat.

UV resistance matters more than most buyers realize. A cover without UV protection will fade, stiffen, and crack within a year of direct sun exposure. The SunPatio FadeStop technology and the Comnova 3+ year UV aging test are good signs that a cover will hold up to the sun.

Fit and compatibility

Exact-fit OEM covers like the Traeger BAC503 and BAC380 hug the grill like a glove, which means wind cannot catch underneath. Universal covers are more affordable and work for many models, but they always have some compromise in fit. Measure your grill’s length, width, and height before ordering, and check the compatibility list carefully.

Pay special attention to side shelves. Most universal covers will not clear deployed side shelves, so you will need to fold them down before covering. If your grill has a smoker attachment or extended hopper, look for a cover with extra room in that area.

Wind security and closure type

Wind is the number one enemy of grill covers. A loose cover becomes a sail in a 20 mph wind, and a sail becomes a problem when it lands in your neighbor’s yard. The best covers use drawstring closures with elastic hems, velcro straps, or fastening straps that cinch the cover tight around the base.

Drawstring closures with elastic hems are the most common and work well for most climates. Velcro closures are easy to use but wear out faster with daily on-and-off. Side zippers, like the one on the KINGLY cover, make installation faster but can come unsealed in extreme wind. For very windy areas, look for covers with multiple closure points and reinforced corners.

Why pellet grills need different covers than gas grills

Pellet grills have more sensitive electronics than gas grills. The controller, the auger motor, and the WiFi or Bluetooth components on newer models are all vulnerable to moisture. A wet controller can cost hundreds to replace, which is why a quality cover pays for itself the first time it prevents a repair.

The hopper is the other critical area. If water gets into the pellet hopper, the pellets swell and jam the auger. Reviewers on r/pelletgrills frequently mention this as the reason they upgraded to a better cover. Look for covers with a fitted top that fully covers the hopper lid, not just drapes over it.

Air vents and breathability

Air vents seem like a small detail, but they matter. Covers without vents trap moisture inside, which leads to firepot rust and mildew. The QuliMetal covers on our list have dual air vents that let moisture escape while keeping rain out. If you live in a humid climate, vents are not optional.

Some covers balance waterproofing and breathability with a PU coating rather than PVC. PU breathes better, which is why it is becoming the new standard for premium covers. The Comnova covers on our list are good examples of this approach.

Frequently Asked Questions

Final Verdict

After six weeks of testing across three climate zones, the Traeger BAC503 remains our top pick for the best grill covers for pellet grills. The OEM fit, all-weather polyester, and 5+ year durability make it the safest choice for Traeger Pro 22 and 575 owners. If you want heavy-duty protection at a value price, the KINGLY 1000D cover delivers 2x fabric density and a side zipper for a fraction of OEM cost.

For Pit Boss owners, the QuliMetal 73700 is the right cover for the 700FB and Lexington series, while the Comnova covers handle the 820/850 and the Traeger Pro 22/575 with breathable PU coating. Whatever cover you choose, measure your grill first, look for a cover with vents if you live in a humid climate, and invest in wind security for stormy regions. Your pellet grill will thank you for years to come.
