(unisex) Xerotherm top features include: flat seams for next to skin comfort and thumb-loops to hold the sleeves in place during donning. These thumb loops should be removed from the thumb and pushed back under the wrist seals prior to diving.

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.
