Fourth Element Xerotherm Beanie Small/Medium

Must-Have Baselayer for Drysuits
The Xerotherm Beanie is the ideal thermal diving beanie for use under a drysuit. Crafted with Polartec Powerstretch, originally developed for NASA, the Xerotherm beanie traps a layer of air next to the skin, providing superior insulation compared to water. This keeps divers drier and more comfortable, whether worn under another undersuit or on its own beneath a neoprene drysuit.

Superior Moisture Control
The unique knit of the Xerotherm fabric delivers the fastest wicking effect among all Fourth Element products. Moisture is drawn through fine fibres and spreads over the outer surface, maintaining a thin air layer next to the skin. This high-performance wicking is so effective that some divers report not noticing minor suit leaks until after their dive.

Expertly Endorsed
The Xerotherm beanie has been rigorously tested in extreme conditions by professionals. Renowned underwater filmmaker Doug Allan praised its performance in -2 degree (29F) water inside the Arctic Circle while filming for the BBC's The Blue Planet. These thermal head protection for scuba diving are also specified by the FBI Dive Teams, Norwegian Navy, and British Police Diving Units for their reliability and effectiveness.

Designed for Ultimate Comfort
This scuba diving beanie is the perfect complement to the rest of the Xerotherm range. Effective wet or dry, the beanie hat is ideal for stashing in a dive bag or the pocket of a BCD to warm up after a dive. Lightweight and low bulk, this beanie offers maximum comfort and thermal protection.
