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 a lightweight, durable hot tub cover with no foam core to waterlog — built to outlast the foam covers it replaces. It's made from the same material premium inflatable paddleboards 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 ZipTech™ zip-on skirts mean there is no custom build: the AIRCAP 1™ comes in six standard sizes covering square spas from 77" to 94" — our Spa Fitter lists more than 1,000 models from 60 brands that take one of them (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 more lifting a heavy, waterlogged foam cover.
Frequently asked questions
Do you offer a guarantee?
Yes. Wrong size, or simply changed your mind: swap it or send it back within 30 days of delivery. We send a prepaid return label and there's no restocking fee; covers must come back in like-new condition with all parts. Bought from an authorized retailer? That retailer's return policy applies. Every AIRCAP 1™ also carries a three-year limited warranty against defects. How the fit guarantee works.
Does the AIRCAP 1™ come with a pump?
Yes, we include our own dual-action pump.
Do you make multiple colors?
Not at this time. We find DEEP GREY™ to be a beautiful addition to any spa.
How many sizes do you make?
Six sizes, covering square spas from 77" to 94" across — about 90% of square hot tubs — and each AIRCAP 1™ includes three skirts for a custom fit.
How much does the AIRCAP 1™ cost?
The AIRCAP 1™ costs $1,195 in every size (77"–94"), including the pump, three ZipTech™ skirt depths, and tie-down straps. A custom foam cover typically lists at about $409–$570 before freight and upgrades (big online cover sellers, checked September 2026) and needs replacing every 3–5 years; the AIRCAP 1™ has no foam to waterlog.
Is the AIRCAP 1™ custom fit?
Choose one of our six sizes that corresponds with your measurements for an amazing, near-custom fit.
Can you repair the cover if punctured?
Yes! Though damage is unlikely thanks to the AIRCAP™'s durability. All covers include a repair kit.
How long does installation take?
Typically 10–15 minutes.
Does the AIRCAP 1™ come with safety straps for children/wind?
Yes — there are four keyed locking tie-down straps.
What is the AIRCAP 1™ warranty?
The AIRCAP 1™ carries a 3-year limited warranty against defects in material and workmanship.
Does the AIRCAP 1™ work with coverlifts?
It works with many manual cover lifters: ones with no hydraulic or gas-spring assistance that do not attach to the cover. See which cover lifters work with AIRCAP, or ask us about yours.
How do I clean my AIRCAP™?
A garden hose and mild soap are all it needs. Pressure washing is not recommended: it can force water into the seams or damage the outer shell.
How much does it weigh?
35–40 lbs depending on the size ordered — and unlike foam, that weight never increases, because there is no foam to absorb water.
Does the AIRCAP™ gain weight over time?
No — by design it weighs the same out of the box through end of life.
How much does a foam hot tub cover weigh?
Foam-cover sellers list new covers at 35–55 lb dry — and a waterlogged one can more than double that.
What if my dog chews my skirt?
Your AIRCAP 1™ comes with three skirts, so you can zip on a new one — or contact us to order replacements.
Do I have to add air to my AIRCAP 1™?
That depends on many factors. You may choose to top it off once or twice a year, but it isn't necessary.
Will hail damage my AIRCAP 1™?
Our durability testing included golf balls fired at the cover at 160 mph to simulate hail. No cover is hail-proof, though: if a storm ever damages yours, call us at (425) 331-9047.
How much weight can my AIRCAP 1™ hold on top?
It is engineered to comply with ASTM F1346-23, the safety-cover standard, which tests that a cover holds a distributed load without letting a child through to the water. That is a safety requirement, not a rating for use as a seat or platform: do not stand, sit, walk or climb on your AIRCAP 1™, and keep its locking tie-down straps fastened whenever the spa is not in use. See safety and ASTM F1346-23 and our safety notice.
