Quick Answer: For most current Traeger owners, the Traeger Woodridge Pro & Elite Grill Cover (BAC775) is the best pellet grill cover — an exact-fit ripstop cover for $99.99-$119.99. Pit Boss owners should buy Pit Boss’s own model-matched covers, priced roughly $34.99-$74.99 depending on the grill. If you own a different brand or just want one dependable cover for less, the Unicook Heavy Duty Waterproof Grill Cover (about $30-$40 in the 55”-70” sizes) is the best universal pick — it won’t match your grill’s silhouette exactly, but it’s genuinely waterproof and fade-resistant. Whatever you buy, an uncovered pellet grill can show firepot rust within a single wet season, so covering it is cheap insurance against the most expensive parts on the machine.
A pellet grill has more exposed metal and electronics than a basic charcoal kettle — a firepot, an auger motor, a hopper, and usually a touchscreen or WiFi controller — and every one of those parts is more expensive to replace than a $30-100 cover. We compared exact-fit brand covers against universal waterproof options to find which actually keeps a grill dry and rust-free through a full season outside.

1. Traeger Woodridge Pro & Elite Grill Cover (BAC775) — Best Overall
Traeger Woodridge Pro & Elite Grill Cover
- Cut to the exact outline of the Woodridge Pro and Woodridge Elite — no gaps for wind or rain to get through.
- Ripstop shell panel resists tearing better than the soft polyester on cheap universal covers.
- Velcro closures at the base keep it cinched down in wind instead of blowing off.
- Priced at a premium versus universal options, and it only fits the Woodridge Pro/Elite footprint.
If you own the Woodridge Pro or Elite, this is the cover to buy — it’s built to Traeger’s own dimensions, so there’s no excess fabric flapping in the wind and no gap at the base where rain sneaks in. Traeger prices it at $99.99 direct, with other retailers listing it as high as $119.99; either way it’s more than a generic cover costs, but it’s also the cover least likely to need replacing after one hard winter.
2. Traeger Ironwood Full-Length Grill Cover — Best for Ironwood
Traeger Ironwood Full-Length Grill Cover
- Full-length exact-fit design for the Ironwood 650 and 885 models.
- Same ripstop-panel construction as the Woodridge cover, sized for the taller Ironwood cart.
- Protects the touchscreen controller, which is the single most expensive part to weather-damage on this grill.
- The most expensive cover on this list — Ironwood owners already paid a premium for the grill itself.
The Ironwood’s touchscreen controller is exposed on the front of the hopper, which makes it more vulnerable to driving rain than the button-and-dial controllers on cheaper grills. Traeger’s own Ironwood cover runs $119.99-$129.99 depending on retailer and is worth the money for that reason alone — a cracked or waterlogged touchscreen is a far more expensive repair than the cover itself.
3. Pit Boss Pro Series Grill Cover — Best for Pit Boss
Pit Boss Pro Series Grill Cover
- Model-matched covers sold directly through Pit Boss's own covers collection for the Sportsman, Pro Series and Pro Series 850/II lines.
- Priced well below Traeger's exact-fit covers while still matching the grill's footprint.
- Weather-resistant fabric that holds up to the Pro Series 850's WiFi/Bluetooth control panel and Flame Broiler housing.
- Fit and material quality vary a bit more by model than Traeger's line — check the specific SKU before buying.
Pit Boss sells covers matched to each grill line directly, and they land far cheaper than Traeger’s exact-fit options — most run in the $34.99-$74.99 range depending on the model, with a mid-size Pro Series 850 cover typically sitting around $40-50. That’s the right buy if you own our best value pick, the Pit Boss Pro Series 850: it protects the WiFi controller and Flame Broiler slide plate for a fraction of what a Traeger-branded cover costs.

4. Unicook Heavy Duty Waterproof Grill Cover — Best Universal / Budget
Unicook Heavy Duty Waterproof Grill Cover
- Sold in multiple sizes (55", 60", 65", 70") to fit most mid-size and large pellet grills, not just one model.
- Fade-resistant fabric with a sealed-seam, waterproof build rated for year-round outdoor use.
- The 55" size runs around $37-48 and the 60" size lists at $39.99 direct from Unicook — both well under any brand-specific option.
- Generic shape means more excess fabric than an exact-fit cover, so it needs the strap/buckle system cinched tight in wind.
If you own a Recteq, Z Grills, Camp Chef, or any brand without a dedicated cover on the market, Unicook is the safe default. It’s genuinely waterproof rather than just water-resistant, the fabric doesn’t chalk and fade the way cheaper vinyl covers do after a summer in direct sun, and at $30-40 it’s a fraction of what any brand-name exact-fit cover costs. Measure your grill’s width, depth and height before ordering — Unicook sells four sizes, and going one size too small means the cover won’t close over the hopper and controller.
How to choose a pellet grill cover
- Buy exact-fit if it exists for your grill. A cover cut to your model’s dimensions blocks wind and rain far better than a generic one, and it lasts longer because there’s no loose fabric to chafe.
- Go universal only when no model-specific option exists, or when you’re covering a grill kept mostly in a garage or under a patio roof, where a looser fit matters less.
- Prioritize the controller and hopper lid, not just the main body — those are the parts that fail first from water intrusion, and the reason cheap tarps don’t cut it.
- Check for a sealed-seam or fully waterproof rating, not just “water-resistant.” Resistant fabrics wet through in sustained rain; waterproof ones don’t.
The bottom line
For most Traeger owners, the Woodridge Pro & Elite Cover or the model-matched Ironwood cover is worth the premium — they’re built to the grill’s exact shape and protect an expensive touchscreen controller. Pit Boss owners get nearly the same protection for less with Pit Boss’s own Pro Series covers. Everyone else, or anyone who just wants one dependable cover without hunting for a brand match, should grab the Unicook Heavy Duty Waterproof Cover.
