WARM

the Xerotherm is the ultimate base layer system for dry suit diving. Designed for versatility it can be used either on its own underneath neoprene drysuits or under a Xerotherm Arctic or other undersuit, with membrane and trilaminate suits.

LIGHTWEIGHT

constructed from a specialised PolartecÆ fabric originally developed for NASA, the unique knit and construction makes Xerotherm the most effective next to the skin garment for ensuring warmth and comfort in demanding environmental conditions.

FAST WICKING

the Xerotherm is made from the fastest wicking fabric in existence. Moisture is moved away from the skin by the fibres of the material and is prevented from contacting the skin. Air, which is a far superior insulator, is held at the skin's surface. This dramatically reduces conductive heat loss from the body.

HARDWEARING

Unique fabric structure and content provides an abrasion resistant outer, which vastly prolongs the life of the garments.

ALL-WAY STRETCH

The Xerotherm gives unrivalled freedom of movement through all-directional stretch, making the wearer more comfortable and able to carry out their diving procedures without restriction.

VERSATILE

worn under membrane suits, as a base layer beneath existing thermal protection, such as a Xerotherm Arctic, the Xerotherm significantly improves a diver's warmth and comfort.

Under neoprene drysuits the low volume, high thermal performance of the Xerotherm provides outstanding protection without loss of freedom of movement.

-Fourth Element’s drybase and Xerotherm products are designed to be used in concert with each other in a layering system. This enables selection of a thermal protection which is appropriate to a wearer’s drysuit and the environmental conditions.
