Fourth Element Xerotherm Beanie Hat
Xerotherm - Thermal Baselayer
The Xerotherm is the ultimate base layer for use under a drysuit. Made using Polartec® Powerstretch® which was originally developed for NASA, the Xerotherm traps a layer of air - a much better insulator than water - next to the skin,keeping the wearer drier and more comfortable. The unisex range is designed to be worn under another undersuit or on its own under a neoprene drysuit and provides astonishing warmth without contributing to bulk or buoyancy.
Xerotherm Beanie Hat
The xerotherm hat, which is warm even when wet, is ideal pre and post dive thermal protection and complements the rest of the xerotherm range.
