Fourth Element Xerotherm Top - Mens

The Fourth Element Xerotherm Top is an ultimate baselayer top 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 knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the Fourth Element range.

Moisture is drawn through the fabric along fine fibres and then spreads 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 range is designed to be worn under another undersuit or on its own under a neoprene drysuit.

Flat seams and a long body of the Fourth Element Xerotherm Top ensure no separation between the top and leggings develops. 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.

"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.
