Fourth Element Xerotherm Mens Vest, Small IEX1_Z0JAC06

Updated for 2018 with new mens and womens 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.
