Meet the AIRCAP 1™ — 8X more durable than foam, never gets heavy, and installs in about 15 minutes. Now available at Professional Pool & Spa.
The AIRCAP 1™ uses AirLoc™ drop stitch technology — the same construction that makes inflatable paddle boards rigid and tough — to create a lighter, stronger, longer-lasting cover with superior protection over foam. Four sizes fit over 90% of hot tubs on the market, so there are no long lead times and no replacing waterlogged foam every 3–5 years.
Patent-pending waterproof zippers with three included custom-length skirts. If a skirt ever wears out (or the dog chews it), just zip on a new one.
Thousands of internal drop-stitch threads trap still air, forming a thermal barrier that holds its R-value for the life of the cover — cutting energy use by up to 30%*.
Welded drop stitch fabric resists punctures, tears, and UV damage, and keeps its shape and rigidity under pressure — season after season.
Less heat escapes, so your spa holds its temperature with less work — the AIRCAP 1™ can cut your hot tub's energy consumption by up to 30%* compared to aging foam covers.
| Cover Type | Annual Energy | Replace Every | 5-Yr Cost |
|---|---|---|---|
| Traditional Foam | $400–$600 | 3–5 years | $2,000+ |
| The AIRCAP 1™ | $280–$420 | 7–10+ years | ~$1,400 |
*Estimates based on average U.S. energy rates and typical hot tub usage. Actual savings may vary.
Install in 15 minutes or less: inflate the two halves with the included dual-action pump, then zip on one of three included custom-length skirts using the patent-pending ZipTech™ system. And if your dog treats the skirt like a chew toy? It's replaceable — no new cover needed.
All you need is the length and width of your spa (or your existing cover). Four semi-custom sizes fit over 90% of hot tubs on the market — and THRML's Spa Fitter™ matches your spa's make and model to the right AIRCAP 1™ in seconds. Stop by Professional Pool & Spa and we'll size it for you.
