No Foam. No Moisture. Longer Life.
Traditional foam hot tub covers can begin breaking down almost as soon as they are installed. Over time, steam, sunlight, and spa chemicals penetrate the foam core, causing it to absorb water, become heavier, develop mold, and lose its insulating ability. Many spa owners find themselves replacing a heavy, waterlogged cover every three to five years.
The AIRCAP 1™ offers a smarter, longer-lasting alternative by eliminating the foam core entirely. Its drop-stitch interior uses pressurized air held between two layers of durable, high-tensile fabric. With no porous foam to absorb moisture, the cover stays lightweight, resists mold and rot, and continues protecting your spa’s heat and energy efficiency year after year.
5-Year Manufacturer Warranty: Foam covers offer 3 years. We offer 5 because we know how it’s built. No moisture absorption. No degradation. No surprises.
