3-Layer Strength Super strong triple layer construction will not rip or tear.
Big, 4 foot overlap for longer wear! We don't skimp on fabric! An extra foot of material provides a better fit, especially on pools with wide top-rails. Extra fabric takes up slack during windy weather, preventing excessive wear and tear.
No more algae growth! Arctic Armor Plus covers are constructed of an extremely tight weave fabric that does not allow light to pass through. Without sunlight, algae cannot grow!
