In 2015 Weber has an ingenious solution for the design & material of its gas grill covers. Made of 100% polyester, the new generation covers are as rugged as vinyl, but more breathable & pliable even in extreme cold conditions. The softness of the fabric also allows for easiest cover placement & removal. Answering the questions of how & where to store the cover, Weber has sewn into the seam a drawstring storage bag that fastens with a hang loop & Velcro. The bag, loop & 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.
