In 2015 Weber has an ingenious solution for the design and material of its gas grill covers. Made of 100 percent polyester, the new generation covers are as rugged as vinyl, but more breathable and pliable even in extreme cold conditions. The softness of the fabric also allows for easiest cover placement and removal. The loop and Velcro are all neatly out of sight when the grill is covered. Providing year-round protection from the environment, these fabric covers carry a generous 3-year limited warranty.
