Fourth Element Xerotherm Vest

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.

The Xerotherm vest provides enhanced thermal protection for the body core when layered underneath a Xerotherm or other undersuit, without increasing bulk around the arms.
