Blue Wave 21-ft Round Above-Ground Pool Winter Cover — Arctic Armor Solid 14x14 Tear-Resistant with Grommets & Winch

The Blue Wave Arctic Armor 21-ft round above-ground pool winter cover is a heavy-duty solid tarp that shields your pool from leaves, rain, snow and sunlight so you can open with far less cleaning in spring.

Closing your pool for winter shouldn't mean tackling a green, debris-choked mess months later. This Arctic Armor cover is engineered as a dense, tear-resistant solid barrier with reinforced, heat-sealed seams and a black underside to limit sunlight and reduce dirt buildup. It ships with the metal grommets, vinyl-coated steel cable and ratcheting winch needed to secure a snug fit on a 21-foot round pool.

How does this cover protect my pool through winter weather?

The Arctic Armor is made from 14x14 laminated scrim polyethylene — a reinforced panel that resists rips and forms a solid shield against leaves, sticks, rain and snow. Heat-sealed seams create a watertight join that helps block moisture and debris from entering the pool.

• Solid (non-mesh) construction keeps surface water and debris out.
• 14x14 laminated scrim adds tear resistance and durability.
• Heat-sealed seams reduce seam failures and block moisture.
• Black underside blocks sunlight to discourage dirt and algae buildup.

Will it stay secure during wind, snow or rainstorms?

Yes — the cover includes rust-resistant metal grommets spaced every 2 feet and a vinyl-coated steel cable plus a ratcheting winch to tension the cover evenly. A 4-foot overlap on the cover helps create a wind-resistant fit around the pool rim.

• Grommets every 2 feet for even attachment points.
• Included vinyl-coated steel cable resists corrosion.
• Ratcheting winch lets you tighten the cover to resist uplift.
• 4-foot overlap ensures coverage and reduces flapping in wind.

How should I care for and maintain the winter cover?

Handle this product as a winter debris cover (not a safety cover) and avoid walking on it or placing weight on top. After heavy snowfall, gently broom excess snow from the edge and use a cover pump to remove standing water that collects on the surface to protect the cover and pool.

• Do not walk on the cover — it is not rated for weight-bearing use.
• Clear heavy snow with a soft-bristle broom to prevent excessive load.
• Use a cover pump for standing water to reduce stress on seams.
• Inspect grommets and cable tension periodically through winter.
