FOURTH ELEMENT Xerotherm Beanie
$39
The Fourth Element Xerotherm is a favorite for our staff. Constructed from ultra premium polartech powerstretch this hat will keep you warm on the surface interval or just looks plain great for everyday wear.
The Fourth Element Xeortherm Hat helps to reduce heat loss through the head, where almost 70% of all the bodies heat escapes. The Xerotherm hat, which is warm even when wet, is ideal pre and post dive thermal protection.
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. 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.
Constructed from Polartec Power Stretch fabric which has been used on several Everest expeditions, the Xerotherm is the most effective next to the skin garment for ensuring warmth and comfort in demanding environmental conditions.
The Xerotherm is made from the fastest wicking fabric in existence. Moisture is moved away from the skin. Air, which is a far superior insulator, is held at the skins surface. This dramaticly reduces conductive heat loss from the body.
