Buffalo Blizzard Supreme 21 ft Round Winter Pool Cover - Heavy Duty

Our review of the Buffalo Blizzard Supreme 21 ft round winter pool cover finds it best suited for owners of 21 ft above ground pools who need a straightforward, heavy duty shield against snow, ice and seasonal debris. The single biggest reason to consider this cover is its reinforced construction: triple-laminated polyethylene with a 10x10 Hold-tite scrim count and double-stitched, triple-thick hems deliver a level of tear resistance and UV protection that many basic covers lack. Installation is simple and the included steel cable, aluminum winch and turnbuckle mean one person can get it secured quickly.

Key Features

• Durable winter protection: The triple-laminated polyethylene and 10x10 Hold-tite scrim count help the cover resist tears, splits and cold-weather cracking for seasonal defense.
• UV and fade resistance: The material and UV-resistant nylon thread used in double-stitched, triple-thick hems reduce sunlight exposure to the pool and help preserve liner appearance.
• Tailored fit: The cover includes an extra 4 ft of material to provide full overlap beyond the pool edge, which improves coverage and helps keep wind from getting underneath.
• Secure installation: Reinforced grommets every 3 ft combined with the supplied steel cable, aluminum winch and turnbuckle make it easy to tension and hold the cover in place.
• Lightweight and manageable: Despite heavy-duty construction, the cover is light enough for one or two people to position and secure without specialized tools.

Who It's For

This cover is aimed at above ground pool owners with a 21 ft round pool who want a no-frills but rugged winter solution that blocks snow, ice and debris. It suits buyers who prioritize a strong scrim count and reinforced hems over premium features like integrated air pillows or custom-fit locking systems.

Those who need a cover for an in-ground pool, a non-standard diameter, or who expect years of heavy-duty commercial use should look elsewhere; some users report variable longevity and note the material feels thinner than some premium market options.
