What Stands Out

  • A long-running top ten seller in Amazon's Grill Covers category and one of the most reviewed covers there
  • Hook and loop straps plus fabric top handles, the two details that separate a cover that stays on from one you chase across the yard
  • Unicook publishes the exact 58 x 25 x 44.5 inch dimension, so you can tape-measure the grill before buying instead of guessing
  • Listed as the same dimension as the Weber 7130 cover, and fits many 3 to 5 burner carts up to 56 in wide
  • Hose it off and air dry, no special cleaner

What To Check

  • The listing says outright that it does not fit 2022 Weber Genesis 300 series grills, so check the model year first
  • No denier weight or UV rating is published, so heavy duty and fade resistant are descriptions rather than measured numbers
  • Not washer or dryer safe

The boring purchase that saves the expensive one. Unicook's 58 inch cover is a vinyl-coated polyester shell cut to 58 by 25 by 44.5 inches, with hook and loop straps at the sides and fabric handles on top. It has been a top ten seller in Amazon's grill covers category for a long stretch and is one of the most reviewed covers there.

The fit list is the useful part: Unicook says it matches the Weber 7130 cover dimension and covers the Genesis II EX, SX and LX 300 models, the Genesis 300 series, and other three to five burner carts up to 56 inches wide.

Cool grill only, and pull the straps snug. The listing states it plainly: the cover goes on after the grill is completely cool. A cover laid over a warm lid is a melted cover at best. Snug straps also keep water from pooling in a slack top, which otherwise turns the lid into a mosquito dish.

The Numbers That Matter

58 x 25 x 44.5 in. Measure your grill at its widest point, lid closed, before you order. This is the whole decision.

56 in max grill width. The cover is 58 inches wide, which leaves room to get it over a 56 inch cart without fighting it.

Straps and handles. Two small features, and the reason a cover is still on the grill in March instead of in the neighbor's fence line.

Who It Is For

Any dad whose grill lives outside year round, which is most of them. If the grill under it is a pellet cooker, Traeger Signature Blend pellets are the fuel that goes with it, and the Grill Rescue bristle-free brush is what keeps the grates clean enough to be worth covering. For the cook itself, the TempPro TempSwift PLUS TP19H is the instant read probe on this shelf.

The Short Version

A grill on a Texas patio takes sun nine months a year and then a hailstorm. This is the simplest way to keep a good grill from turning into a rusty one, and the 58 inch size matches the Genesis and Genesis II 300 series footprint a lot of dads already own. Measure the grill and check the model year before ordering, because fit is the only thing a cover has to get right.
