Heavy Duty 4' x 5' and 4' x 8' Air Pillow

Protect your pool from winter ice damage with heavy-duty ice equalizing air pillows. Made from thick 4mm PVC vinyl, these pillows stay inflated when thinner alternatives collapse—helping prevent leaves and debris from settling on your cover. Built to handle harsh conditions, the extra-thick construction withstands heavy snow and ice pressure. Double-sealed edges provide superior leak resistance and long-term durability. Engineered for extreme cold, the flexible vinyl resists cracking down to -25°F, making it ideal for northern climates. Each pillow includes 55 ft. of durable anchoring rope for secure, stable placement. Designed for convenience, the integrated check valve allows for quick inflation with a standard pump and easy deflation when opening your pool in the spring.
