The CORE base layer is designed to regulate
your body temperature at the base level through all weather conditions. The
compression weave is designed to cling tight to the body to help with muscle
fatigue and rapid wicking.
Using a densely woven, lightweight, micro denier 100% polyester yarn, you get very high warmth-to-weight ratio without the usual weight and bulk of traditional fleece. Can be used as an insulation layer in changeable weather, or as a next-to-skin layer in cooler weather.
