Fourth Element Xerotherm Top, size S - Black

The ultimate baselayer. 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 drysuit. 53% Polyester / 38% Nylon / 9% Elastane
