Orca Thermal Neoprene Swim Cap
£35.00
Built for cold-water open swimming, this neoprene cap uses 3mm thermal neoprene and a soft thermal lining to trap heat and cut down on heat loss during long sessions. An adjustable Velcro chin strap gets you a snug, secure fit without the chafing that cheaper thermal caps are known for.
Key Features
- 3mm Thermal Neoprene — thicker than a standard silicone or latex cap, built specifically for cold-water insulation.
- Thermal Lining — traps additional heat and reduces heat loss throughout the swim.
- Adjustable Velcro Chin Strap — dials in the fit to your head shape rather than a generic stretch fit.
- Anti-Chafe Design — soft lining reduces rubbing at the chin and ears, a common complaint with thermal caps.
- Unisex Sizing — three sizes covering a broad range of head circumferences.
Description
Orca Thermal Neoprene Swim Cap
Stay Warmer, Swim Longer
Open water sessions get a lot less comfortable once the water temperature drops — and most heat loss happens through the head. Orca’s Thermal Neoprene Swim Cap tackles that directly: 3mm thick neoprene paired with a thermal lining is built to trap heat and keep you swimming for longer in cold conditions, whether that’s an early-season lake swim or a winter open water session.
Fit and Comfort
The cap uses a Velcro chin strap so you can adjust it to the shape of your head rather than relying on a one-size stretch fit. That, combined with the soft thermal lining against the skin, is designed specifically to prevent the chafing around the chin and ears that’s common with thicker neoprene caps.
