My old cover started tearing after one year. Have searched everywhere. Wasn't sure how to interpret "polyester" in the descreption, thought it might be thin and weak. However, this Patio Armour cover is real heavy and woven. The cover looks better than my barbecue. Extremely classy look. Extreme quality. Fits my 55 in grill perfectly and easy to slide on and latck tight. This is the best one out there but on where near the most expensive.
