What customers say
Customers overwhelmingly praise the Buffalo Blizzard Supreme Plus cover for its superior durability and robust construction, making it ideal for harsh winters. Its exceptional thickness handles heavy snow and ice loads effectively, providing significant peace of mind compared to lighter options. This longevity is the primary driver of satisfaction, justifying the higher initial investment for users prioritizing protection. A consistent point of friction, however, is the cover's notable weight and bulk, which often complicates the installation and removal process, frequently requiring assistance. While the cover material earns high marks, some users feel the included cable and winch accessories lack the same substantial quality. Overall, the consensus views this heavy-duty protection as a worthwhile, long-term investment for serious pool owners.
Know before you buy
Yes, the cover is designed specifically for 15' x 21' oval above-ground pools. It includes a 4-foot overhang, which provides enough extra material to drape over the top rails and secure properly with the included cable and winch system.
The cable and winch system pulls the perimeter of the cover tight against the pool wall, preventing wind from getting underneath. For added security, the cover features double grommets every three feet, allowing you to further anchor it if you live in an area with particularly harsh weather.
This is a solid barrier cover, meaning it does not allow water or debris to pass through into your pool. This design is intended to keep your pool water clean and clear by blocking sunlight, which helps prevent algae growth during the off-season.
The cover is made from triple-laminated polyethylene, which is engineered to be lightweight for easier handling. While one person can typically manage the installation, having a second person to help spread the cover evenly across the pool will make the process much faster.
The 12 x 12 scrim count refers to the density of the weave within the polyethylene material. A higher count indicates a tighter, more durable weave, which provides better resistance against tearing and punctures from winter debris.
While the cover is UV-resistant to protect the material from sun damage during the winter, it is specifically designed as a winter cover. It is best to remove it once the swimming season begins to prevent heat buildup and potential damage to the pool liner.
