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 Socks provide excellent thermal protection and comfort. Constructed using flat locked stitching and single layer high wicking fleece fabric, they protect the extremities and complement the xerotherm undersuit range. They are low bulk and can be worn under other thermal socks without preventing making drysuit boots too tight or uncomfortable.
