Fourth Element Xerotherm Vest Mens

Fourth Element’s Xerotherm range is a great baselayer for wearing with 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 under your neoprene drysuit, or with another undersuit for extra thermal protection. 

The vest is a great option if you just need an additional layer of warmth on your core. The sleeveless design means there is no restriction of movement to the arms. It has very minimal bulk so you don’t feel too layered, and also minimal effects on your buoyancy. 

The fabric is the fast wicking, removing moisture and perspiration from the skin then spreading this out on the external layer of the material, maintaining the layer of air between the material and your body.

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