FOURTH ELEMENT – Xerotherm Set

The Fourth Element 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.

The three piece set comprises top, leggings and socks, providing top to toe thermal protection throughout the dive. Adding a vest to make up a xerotherm plus, gives extra protection to the body core without significantly affecting wearer’s buoyancy. In fact the buoyancy effects of the xerotherm are so small that they rarely impact on weight configuration, yet dramatically improve warmth.

“The performance is superb”. This was the reaction of Doug Allan, world renowned and award-winning underwater filmmaker and author after testing the xerotherm in -2 degree (29F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet.

The xerotherm represents the ultimate in base layer performance, unrivalled by anything else on the market. Since Doug’s testing, the Fourth Element 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.
