Made from a thick 16-mil polyethylene resin, it offers durability and can resist tears, which is great if you want a long-lasting cover. Its round shape fits 16-foot pools, and the cover is easy to trim for a perfect fit around ladders or steps. The silver-gray color is not only stylish but also helps block harmful UV rays, protecting the pool water and the cover itself.
