Arctic Armor’s 15-year Solid In-Ground Winter Cover is crafted from durable polyethylene with a 14x14 scrim count. This cover effectively protects your pool from winter elements by preventing water penetration. Reinforced heat-sealed seams add extra strength, while the black underside helps ensure a clean pool in the spring. It features a generous 5-foot overlap for a proper fit. Integrated loops are spaced every four feet to secure water tubes and reinforced corner grommets allow for extra security. Water tubes are sold separately. Backed by a 15-year warranty, with the first 3 years fully covered.
