The Fourth Element Xerotherm Beanie Hat helps to reduce heat loss through the head. It is warm even when wet, which is perfect for pre and post dive thermal protection. And you'll look like a true professional!
Great for Diving and Everyday Use.
The Xerotherm is the ultimate base layer for use under a drysuit. 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.
Xerotherm - Fast Wicking Baselayer
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 (a more efficient insulator than water) next to the skin.
"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 Centigrade (29°F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet.
The Fourth Element Xerotherm represents the ultimate in base layer performance, unrivalled by anything else on the market. Since Doug's testing, the xerotherm has been to the top of Everest and down to the Titanic, as well as being specified by the FBI Dive Teams, Norwegian Navy and British Police Diving Units.
