Fourth Element Xerotherm Beanie Hat

Fourth Element Xerotherm Beanie

Fourth Element Xerotherm Beanie Hat, is the perfect complement to the rest of the Xerotherm range. Effective wet or dry, the beanie hat is the ideal thing to stash in a dive bag, or even the pocket of a BCD to put on to warm up after a dive. Fourth Element Xerotherm is the ultimate baselayer for use under a drysuit and 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 wicking 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 performance is superb". This was the reaction of Doug Allan, world-renowned and award-winning underwater filmmaker and author after testing the Xerotherm in -2 degree (29F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet.
