Fourth Element Xerotherm Socks

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.

Designed to be worn under a padded undersuit or on its own under a crushed neoprene drysuit, it provides astonishing warmth without contributing to bulk. Under crushed neoprene suits the low volume, high thermal performance of the Xerotherm provides outstanding protection without loss of freedom of movement.
