Our CoverMates Ultima polyester built in grill cover is an excellent choice because the fabric is specially treated to make it highly water-resistant, yet breathable. Covers that breathe are superior because they allow moisture a way to escape instead of being trapped, causing the possible development of mold, mildew and rust.

Polyester is also preferred during the cold winter months because it remains soft and flexible and does not get stiff and brittle and susceptible to cracking like less expensive vinyl materials.  It is much more lightweight and easy to handle, so putting our built in grill cover on and taking it off is a snap. The elastic hem and drawcord keeps the cover in place, and each Ultima cover comes with an industry-leading 7-year warranty.
