The Fourth Element Xerotherm Mens Top is a thermal baselayer made to keep you dry and warm in your drysuit. The Soft internal lining is comfortable against the skin and wicks moisture away very quickly so you stay dry. The material was originally designed for NASA and has since been used for filmakers as well as the FBI, Navy and Police diving teams as well as explorers from deep down to the Titanic up to the top of Everest.

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 collection 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. 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. Outstanding thermal performance Lightweight Low bulk and buoyancy Extremely fast wicking Hardwearing Machine washable Performs when wet
