Blue Wave Arctic Armor 21-ft Round Above-Ground Pool Winter Cover, Navy — Heavy-Duty Solid with Heat-Sealed Seams

The Blue Wave Arctic Armor 21-ft round above-ground pool winter cover is a heavy-duty solid tarp that blocks leaves, rain, snow and sunlight so your pool reopens cleaner after winter.

Closing your above-ground pool for the off-season shouldn’t mean a spring of skimming, vacuuming and chemical correction. The Arctic Armor cover from Blue Wave is built from 7x7 scrim woven polyethylene with reinforced, heat-sealed seams and a black underside to form a solid, tear-resistant barrier against debris, moisture and UV exposure. It ships with the vinyl-coated cable, metal winch and rust-resistant aluminum grommets you need to fasten a snug, wind-resistant fit for a 21-foot round pool.

How does this cover keep debris and moisture out all winter?

The cover’s dense woven scrim and sealed seams create a continuous, solid surface that stops leaves, twigs, rain and melting snow from entering the pool water. Since it’s a solid tarp rather than a mesh, water does not pass through the fabric and sunlight is blocked so organic growth is reduced beneath the cover.

• 7x7 scrim woven polyethylene resists tearing and punctures
• Heat-sealed seams provide a watertight bond across panels
• Black underside blocks sunlight to limit dirt and algae buildup
• Solid panel construction reduces winter evaporation

What hardware is included and how is the cover secured?

Blue Wave supplies rust-resistant aluminum grommets spaced every 2 feet, a vinyl-coated cable and a metal winch so you can cinch the cover around the pool perimeter. The cable threads through the grommets and tightens with the winch to hold the 4-foot overlap in place and resist wind and snow loads.

• Aluminum grommets prevent corrosion and distribute tension evenly
• Vinyl-coated cable resists wear and won’t cut the cover edge
• Included metal winch lets you tighten the cover for a snug fit
• 4-ft overlap simplifies centering and improves wind resistance

How should I care for the cover during and after winter storms?

The Arctic Armor is designed as a debris-cover, not a safety platform; avoid walking on it or loading it with weight. After heavy snowfall, remove excess snow from the pool edge with a soft-bristle broom and use a cover pump to remove standing water that accumulates on top of the tarp.

• Do not walk on the cover or allow heavy loads
• Brush snow from the perimeter after major storms
• Use a cover pump to remove pooled water and extend fabric life
• Inspect grommets and cable tension periodically through winter

U.S.-based customer support and more than three decades of industry experience are available if you need help with sizing, installation or warranty service.

Who this product is for: The Blue Wave Arctic Armor 21-ft round winter cover is ideal for owners of 21-foot above-ground pools who want a low-maintenance winter solution that keeps out debris and limits water evaporation. It’s best for homeowners seeking a durable, solid tarp with included hardware for a secure fit, rather than a cover rated for weight-bearing safety. If you want a cover that reduces spring cleanup and includes the cable and winch needed for installation, this model is built for that purpose.
