XEROTHERM
THE ULTIMATE THERMAL BASELAYER
The fastest wicking thermal baselayer on the market, tried and tested in some of the most extreme environments on the planet. The xerotherm is specified by the FBI and many other professional dive teams.
Updated for 2018 with new men’s and women’s fits. The ultimate baselayer for use under a drysuit. Made using Polartec® Powerstretch® 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. The range is designed to be worn under another undersuit or on its own under a neoprene drysuit.
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 next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive.
“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 (29F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet.
The Xerotherm represents the ultimate in baselayer 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 Unit.

PRODUCTS IN THE RANGE
Xerotherm Long Sleeve Top
MEN’S AND WOMEN’S
With flat seams and a long body to ensure that no separation between top and leggings develops, the top is the ideal next-to-skin layer under a drysuit. Thumb loops keep the sleeves in place whilst donning the drysuit and should be removed from the thumb and pushed back through the wrist seals prior to diving.
Xerotherm Vest
MEN’S AND WOMEN’S
The perfect addition to a diver’s thermal protection, the vest enhances the warmth of the body core without significantly affecting bulk or buoyancy. Freedom of movement of the arms is also maximised, thanks to the sleeveless design
Xerotherm Leggings
MEN’S AND WOMEN’S
These simple, minimalist leggings have been designed for maximum performance. The high waistband ensures good overlap of the top and leggings and unique foot pocket design ensures the leggings do not ride up. Flat seams provide next-to-skin comfort throughout the dive.
Xerotherm Beanie Hat
This is the perfect complement to the rest of the Xerotherm range. Effective wet or dry, the beanie hat is the ideal thing to stash in a dive bag, or even the pocket of a BCD to put on to warm up after a dive.
Xerotherm Socks
Excellent thermal protection and comfort. Thin enough to be worn under other drysuit socks yet capable enough as thermal protection in their own right, they are comfortable thanks to the flat locked seams and fast wicking fabric.
Xerotherm Gloves
Cold fingers are often the first telltale signs of exposure on a long dive. The Xerotherm gloves provide excellent thermal protection as dryglove liners without being bulky, allowing for maximum dexterity.
Low-profile stitching offers comfort and greater sensitivity, and when used in conjunction with the Xerotherm wrist warmers and the original Xerotherm suit, the gloves complete (finger)tip to toe protection for the ultimate base layer.
The Xerotherm gloves also make excellent glove liners for use above water. Silicone fingertip protection provides extra grip and durability in key wear areas.
