XEROTHERM -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.

Now updated for 2018 with new fits for men and women.

The ultimate baselayer for use under a drysuit. Made using Polartec© Powerstretch© 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 range is designed to be worn under another undersuit or on its own under a neoprene drysuit. 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.

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
