The Nash ZT Base Layer Set is a versatile base layer for both cold and warm conditions. The set consists of a long-sleeved top and pants. When worn directly on the skin, the garments will retain body heat. The top can also be worn separately in warmer temperatures, with the long sleeves protecting against UV rays and insects. The soft and stretchy material allows for maximum freedom of movement and prevents creeping up under top layers or in a stretcher.
