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.

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.
