Fourth Element Xerotherm Three Piece Undergarment Set - Mens

The Fourth Element Xerotherm 2018 Three Piece Undergarment Set comprises a Xerotherm Top, Leggings and Socks, providing top to toe thermal protection throughout the dive. The buoyancy effects of the Xerotherm are so small that they rarely impact on weight configuration, yet dramatically improve warmth. This undersuit set comes complete with a Fourth Element nylon carry bag.

The Fourth Element Xerotherm Top has thumb-loops to hold the sleeves in place during donning. These thumb loops should be removed from the thumb and pushed back under the wrist seals prior to diving.

The Fourth Element Xerotherm Leggings have stirrups to ensure the leggings stay in place whilst donning a drysuit.

Separation of the Xerotherm Leggings from a Xerotherm Top undergarment is prevented by the high waistband of the Leggings, combined with the long hem of the Top, which can be securely tucked into the bottom part's waistband.

The Fourth Element Xerotherm Drysuit Socks provide excellent thermal protection and comfort for the feet!

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.

Xerotherm - Fast Wicking Baselayer
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 (a more efficient insulator than water) next to the skin.

"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 Centigrade (29°F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet.

The Fourth Element Xerotherm represents the ultimate in base layer 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 Units.

Xerotherm is Machine Washable
Machine wash cold. Line dry. Do not use bleach. Do not iron. Do not tumble dry. Can be dry cleaned. Avoid the use of fabric softeners.
