The fastest wicking thermal baselayer on the market, tried and tested in some of the most extreme environments on the planet. The xerotherm is specified by the FBI and many other professional dive teams. These simple, minimalist leggings have been designed for maximum performance. The high waistband ensures good overlap of the top and leggings and unique foot pocket design ensures the leggings do not ride up. Flat seams provide next-to-skin comfort throughout the dive.
