Arctic Armor 21-Ft round above Ground Pool Winter Cover, Navy | Solid Polyethyle

Securing the cover is straightforward. The 4-ft overlap extends well beyond the pool wall for a snug, wind-resistant fit, and a helper makes installation faster on a pool this size. It’s made with a 7×7 scrim woven polyethylene, a dense, tear-resistant material that forms a solid barrier against leaves, sticks, rain, and snow.
