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

Our review of the Buffalo Blizzard Supreme Plus 21 ft round winter pool cover finds it best suited to owners of above ground pools who need straightforward seasonal protection without a heavy installation job. The single biggest reason to buy is its tailored overlap and reinforced fasteners, which keep the cover securely seated over a 21 ft pool and block snow, leaves and sunlight. It is clearly designed for practical winter defense rather than luxury durability, and performs well for customers who want an affordable, easy-to-install winter solution.

Key Features

• Durable Winter Protection: The 12x12 Hold-tite scrim construction resists tearing and cracking so the cover can shield the pool from snow and ice.
• UV & Fade Resistant: The material reduces sunlight exposure to help preserve water clarity and protect the liner's appearance.
• Reinforced Hems: Double-stitched, triple-thick hems with UV-resistant nylon thread provide extra edge strength against wind and abrasion.
• Tailored Fit: An additional 4 ft of overlap beyond the pool edge helps prevent wind from slipping under the cover for more reliable coverage.
• Secure Installation: Reinforced grommets every 3 ft plus the included steel cable, aluminum winch and turnbuckle make it straightforward to tighten and hold the cover in place.
• Weather Tough: Triple-laminated polyethylene construction is made to withstand freezing temperatures, high winds and extended sun exposure.

Who It's For

This cover is aimed at above ground pool owners with a 21 ft round pool who want an easy, lightweight solution to keep out seasonal debris and limit sunlight exposure. It is ideal for those who prefer a simple install using a cable and winch and who value overlap and reinforced grommets for a secure fit.

Customers seeking an ultra-heavyweight industrial cover or long-term warranty-backed material should look elsewhere; some users report the material feels thin and may not last many seasons under heavy stress. For winter-only protection and good value, however, this cover is a practical choice.

Pros & Cons
