Blue Wave Arctic Armor 21-ft Round Mesh Winter Pool Cover — woven polyethylene, rust-resistant cable

Blue Wave Arctic Armor 21-ft Round is a rugged mesh winter cover that keeps leaves and debris out while allowing rain and snowmelt to drain through for easier spring opening.

Designed for 21-foot round above-ground pools, this Arctic Armor mesh cover balances protection and manageability so closing your pool doesn’t become a season-long chore. The woven polyethylene mesh blocks sticks and leaves but permits water to pass, preventing standing water and heavy ice buildup on top of the cover. Included hardware—heavy-duty grommets, a rust-resistant vinyl-coated cable, and a metal locking winch—lets you secure the cover quickly and store it compactly until spring.

How does this cover prevent water and ice buildup?

The fine woven mesh construction allows rain and melting snow to trickle through the cover into the pool rather than pooling on top where it can freeze. That drainage minimizes weight from ice and reduces the need to manage trapped water during cold snaps. Because water drains slowly, there’s no standing water that would otherwise stretch or damage the cover.

• Fine polyethylene mesh that permits slow drainage
• Mesh design prevents heavy pooling and ice formation
• Lightweight material for easier handling during freeze/thaw cycles

What comes in the box and how do I install it?

Everything needed to secure the cover is included so you can install it without shopping for extra parts. Spread the cover over the pool, thread the supplied vinyl-coated cable through the rust-resistant metal grommets spaced around the perimeter, and tighten with the metal locking winch. The cover also includes a 4-foot overlap to extend down the pool wall for added protection.

• Cover sized for 21-ft round pools with 4-ft overlap
• Heavy-duty metal grommets spaced every two feet
• Rust-resistant vinyl-coated cable and metal locking winch

How durable is the Arctic Armor mesh through winter weather?

Made from woven polyethylene, the cover stands up to a full winter season of snow, ice and freezing temperatures without excessive sagging or tearing. The mesh resists tears and remains lightweight for easier removal in spring. Blue Wave supports the product with an eight-year limited warranty for added peace of mind.

• Woven polyethylene resists wear from snow and ice
• Lightweight construction simplifies fall installation and spring removal
• Backed by Blue Wave’s 8-year limited warranty and U.S.-based support

When should I install and remove the cover?

Install the Arctic Armor cover in late fall before the first hard freeze to keep debris out and reduce winter maintenance. Remove it in early spring once thawing begins to reveal a cleaner pool and less debris to scoop. The cover folds compactly for off-season storage until the next closing.

• Install in late fall before first freeze
• Remove in early spring during thawing for easiest cleanup
• Folds compactly for offseason storage

Who is this for: The Blue Wave Arctic Armor 21-ft Round Rugged Mesh Pool Cover is aimed at above-ground pool owners who want a low-maintenance winter solution that keeps debris out, minimizes ice weight, and simplifies spring opening. It’s ideal if you prefer a no-pump drainage approach, need a complete hardware kit included, and value a durable mesh that stays lightweight for easier handling. Note: this product is intended to protect from the elements, not to serve as a safety cover.
