The Xerotherm is the ultimate base layer for use under a drysuit. Made using Polartec® Powerstretch®, originally developed for NASA. Air is a better insulator than water, the Xerotherm traps a layer of air 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. The Xerotherm has been in -2 degree water inside the Arctic Circle, to the top of Everest and down to the Titanic, as well as being specified by the FBI Dive Teams, Norwegian Navy and British Police Diving Units.
