New Artic Armor Blue Winter Round Above Ground Swimming Pool Cover 30' NEW Artic Armor 30' Round Winter Above Ground Pool Cover Premium Quality 4-FOOT OVERLAP FOR BETTER WEAR! - We do not skimp on fabric! Arctic Armor above-ground covers use an extra foot of material-another reason why they are a great value! A 4-ft. overlap provides a better fit, esp. on pools with extra wide top-rails. This extra fabric also takes up some of the slack during windy weather, helping to prevent excessive wear and tear. STRONG, LONG-LASTING WOVEN STRANDS - Arctic Armor covers are woven strong/long-lasting polyethylene tapes to produce a cover that will hold up to winters worst. NO MORE ALGAE GROWTH! - Arctic Armor covers are constructed of an extremely tight weave fabric that does not allow light to pass through. Without sunlight, algae cannot grow!
