Our above-ground covers have sewn seams and reinforced perimeter binding with high grade nylon webbing loops. Above-ground covers come with a domestic made wire/winch combo to ensure easy installation. We are also an importer of woven poly winter covers for inground and above-ground applications. Imported covers come in green or blue. Standard poly covers come in blue or tan.
