Fourth Element Xerotherm Top Mens

Fourth Element’s Xerotherm range is the ultimate baselayer for your drysuit. The Polartec® Powerstretch® material, originally developed for NASA, traps a layer of air between your skin and the material, providing excellent comfort and thermal protection. The Xerotherm range can be worn alone as an undersuit, or underneath another undersuit for extra thermal protection. 

The long sleeve top has thumb loops to help with the ease of donning your drysuit, though these need to be pushed back inside the seals of your suit to prevent leakages. Designed with flat seams for comfort and a long body to help ensure there is no separation between the top and leggings. 

The fabric is the fasted moisture wicking of any of Fourth Element’s ranges, removing 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. Many divers have not even noticed minor leaks from their drysuit as this system is so effective. 

Xerotherm is popular with FBI Dive Teams, the Norwegian Navy and British Police Dive Units.
