Buffalo Blizzard Supreme Plus 18 ft x 40 ft Rectangular Winter Pool

In this review of the Buffalo Blizzard Supreme Plus 18 ft x 40 ft rectangular winter pool cover, the bottom line is simple: this cover is best for pool owners who want strong seasonal protection against snow, ice and debris with a snug fit and UV resistance. The reviewer found it effective at keeping leaves and winter grime out of the pool and appreciated the extra 5 ft of overlap that helps keep wind from getting underneath. While functionality, fit, and the tan/silver appearance are genuine strengths, there are mixed reports about material thickness and long-term durability that every buyer should consider.

Key Features

• Durable winter protection: The 12x12 Hold-tite scrim count resists tears and cold-weather cracking so the cover can withstand winter loading.
• UV and fade resistant: UV-resistant nylon thread and materials reduce sunlight exposure to preserve water clarity and protect the liner's appearance.
• Tailored fit: An additional 5 ft of material provides full overlap beyond the pool edge for a more secure coverage that helps prevent wind uplift.
• Secure installation: Heavy-duty water bag loops every 4 ft and evenly spaced grommets hold water bags and fasteners in place to anchor the cover through the season.
• Rugged construction: Triple-laminated polyethylene with double-stitched, triple-thick hems gives long-lasting strength against freezing temperatures and high winds.

Who It's For

This cover suits owners of rectangular above ground pools who need a heavy-duty seasonal shield against snow, leaves and sun exposure and who value a close fit around the pool perimeter. The extra overlap and frequent water bag loops make it a good option when wind and winter debris are primary concerns.

Those who should look elsewhere are buyers seeking the thickest possible industrial-grade fabric or guaranteed multi-year durability; some customers reported thinner-feeling material and mixed long-term results, so if absolute maximum thickness is essential, consider a heavyweight commercial option.

Pros & Cons

Pros
