Fourth Element's Xerotherm range is the ultimate baselayer for your drysuit. The Polartec® Powerstretch® material, works by trapping a layer of air between your skin and the material, providing excellent thermal protection. Originally designed for NASA where only the best is good enough. The Xerotherm range can be worn alone as an undersuit for neoprene drysuits, or next to your skin with another undersuit for extra thermal protection. 

The leggings have a minimalist design but with maximum performance. Designed with a high waist to prevent separation with the top and secure foot loops so the leggings don't ride up. Flat seams have been used for next to skin comfort.

The fabric offers the fastest moisture wicking of Fourth Element's ranges, pulling perspiration and moisture from the skin and spreading this out on the external layer of the material, maintaining the layer of air between the material and your body. Minor leaks in a drysuit have not been noticed by users when wearing the Xerotherm undergarments as this is so effective.  

Xerotherm is preferred by FBI Dive Teams, the Norwegian Navy and British Police Dive Units.
