These pool covers are designed for round above ground pools. They will keep your pool free of dirt, insects, leaves and debris. Made from polyethylene, the pool cover weighs just 90 g/m² and is tear-resistant and water-repellent. Thanks to the small drainage holes in the middle, this pool cover allows water to run through instead of collecting at the top. The small drainage holes also ensure good ventilation. The high quality workmanship of the seams at the hem ensures years of use. The pool cover is easily attached to the pool by tightening the lines with stoppers around the pool.
