25' Winter Cover for 21' Round Pool 15 Yr. Royal

Constructed of our strongest and most tear resistant material. This cover features rugged U.V. stabilized woven polyethylene that protects it from sun, snow, wind and ice. It features a black underside to retard algae growth and heat sealed seams to ensure a crystal clear pool next spring. The cover has a big 4 foot overlap that means it will fit pools with wider top rails and will not stretch and rip like smaller 3 foot overlap covers.

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' overlap provides a better fit, especially on pools with extra wide top ledges. 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!

The cover is held secure on your pool with a heavy duty vinyl coated cable and tightener that is anchored by rip proof metal grommets. This cover is backed by a 15 year pro-rated warranty (3 years full) and is royal blue with a black underside.
