Fourth Element Xerotherm Features

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.
