The Xerotherm range is the ultimate base layer for use under a drysuit. Made using Polartec® Powerstretch®, 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 providing astonishing warmth without contributing to bulk or buoyancy.

The xerotherm vest provides enhanced thermal protection for the body core when layered underneath a xerotherm or other undersuit, without increasing bulk around the arms.
