The Fourth Element Xerotherm is the ultimate base layter 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, or in the summer months under a trilaminate suit and provides astonishing warmth without contributing to bulk or buoyancy.
The xerotherm has been 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.
The set consists of a long sleeve top, pants and socks. Each component is designed to be worn overlapping and the pants have a stirrup system to ensure they stay in place no matter the adventure.
With a range of other accessories such as a beanie, wrist warmers and snug, the Fourth Element Xerotherm range will quickly become your favorite base layer both in the water and out.
