Xerotherm socks

The ultimate base layer for wearing under a drysuit. Made from Polartec® Powerstretch®, a material originally developed for NASA, Xerotherm traps a layer of air – a far more effective 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 knitted structure of the Xerotherm material offers the fastest moisture wicking in the entire fourth element range. Moisture is drawn through the fine fibers and distributed across the outer surface, maintaining a thin layer of air next to the skin. The efficiency is so high that some users report small leaks in the suit during the dive, without noticing them until the end.

"The performance is superb" – this was the reaction of Doug Allan, famous underwater filmmaker and award-winning author, after testing the Xerotherm in -2°C water, in the Arctic Circle, in Svalbard, while filming for the BBC production The Blue Planet .

Xerotherm is used by FBI dive teams, the Norwegian Navy, and British Police dive units.
