Product Description

UnDWool HC™ is a performance base layer for cycling, running or any of your outdoor pursuits. The 150 gram fabric weight has everything we love in a base layer. It starts with a natural 18.5 micron Merino wool combined with a layer of polyester to add stability and strength. The jersey knit construction has the perfect amount of stretch without the additional weight of spandex. Wearing UnDWool on your skin provides comfort through varied weather conditions and aerobic intensity levels. UnDWool has superfine Merino fibers that are soft and comfortable on-the-skin, not prickly or nervy. It offers moisture control, odor resistance and core temperature regulation in cool to cold weather. UnDWool can be worn on its own or as a base layer.
