AIRCAP 1™
The Hot Tub Cover You Deserve.
Designed by a 25+ year spa industry veteran — the lightest, most durable, longest-lasting cover we could build.
The AIRCAP 1™ was conceptualized and designed by a 25+ year spa industry veteran. After years of being asked by customers whether there was anything else out there other than the 40-year-old foam-wrapped-in-vinyl technology, we can finally say yes!
The AIRCAP 1™ is the lightest-weight, most durable, longest-lasting hot tub cover ever built. It's made from the same material the best inflatable paddleboards in the world are made from, and our manufacturing facility uses the best quality-control practices found in the top paddleboard brands. We use our AirLoc® process of heat-welding all components, ensuring the AIRCAP 1™ is built to withstand the elements for years to come.
Our patent-pending Ziptech™ system gets you a replacement cover fast, too. We understood that waiting 8–10 weeks for a replacement foam cover was a pain, so we fixed that while we were at it. The AIRCAP 1™ comes in four sizes that we found cover 90% of the hot tubs on the market (yes, we're working on more sizes).
Simply measure your spa side to side and front to back. Take those two measurements and, using our SureFit® guide, quickly find the right AIRCAP 1™ size for you. Once your AIRCAP 1™ arrives and you've inflated it, zip on one of the three included skirt sizes for an incredible, long-lasting cover — installed in minutes.
Your AIRCAP 1™ will be an amazing semi-custom fit for your spa, and we're confident you and your family will love using your hot tub with it — no longer having to deal with heavy, waterlogged, mold-infested foam covers again!
