Fourth Element Xerotherm 3 Piece Contains: Fourth Element Xerotherm Leggings Fourth Element Xerotherm Top Fourth Element Xerotherm Socks The Xerotherm is the ultimate base layer system for dry suit scuba diving. It can be used either on its own under crushed neoprene or under a Thinsulate to augment a diver's existing thermal protection. 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 & 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 dramatically reduces conductive heat loss from the body. Worn under membrane suits, as a base layer beneath existing thermal protection, the Xerotherm significantly improves a diver's warmth & comfort. Under crushed neoprene suits the low volume, high thermal performance of the Xerotherm provides outstanding protection without loss of freedom of movement. 1.) High waisted leggings with flat tape ensures no separation of top & leggings. Flat seams are used throughout to maximise next to the skin comfort. 2.) Secure foot pockets ensure leggings stay in place whilst donning a drysuit. On the top, thumb loops prevent sleeves from riding up. 3.) Almost 70% of heat is lost through the head. The xerotherm hat, which is warm even when wet, is ideal pre & post dive thermal protection. 4.) The Xerotherm vest is the perfect accompaniment to a xerotherm for extra protection for the body core. Comfortable & warm, it can make all the difference on a long deco stop.
