The Xerotherm Arctic socks are the UGG's of the dive world - these socks will keep your toes toasty in pretty much any conditions. Xerotherm is made using Polartec® Powerstretch® which was 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.
Designed to be worn under a padded undersuit or on its own under a crushed neoprene drysuit, it provides astonishing warmth without contributing to bulk.
