THE ULTIMATE THERMAL BASELAYER

The fastest wicking thermal baselayer on the market, tried and tested in some of the most extreme environments on the planet. The xerotherm is specified by the FBI and many other professional dive teams.

The perfect addition to a diver’s thermal protection, the vest enhances the warmth of the body core without significantly affecting bulk or buoyancy. Freedom of movement of the arms is also maximised, thanks to the sleeveless design

The knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the fourth element product range. Moisture is drawn out through the fabric along fine fibres and then spreads out over the outer surface. This maintains a thin layer of air next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive
