The Casper heavyweight hunting base layer shirt combines the power of Heat Boost™ graphene technology with a super cozy soft hand feel to provide all day warmth. It is designed for cold temperatures to help you outlast the cold and stay out longer.Graphene yarn knitted into the knit jersey has the thermal conductivity, moisture wicking, and scent control properties inherent to graphene. The graphene harnesses your body’s energy, absorbs the heat and releases it back, surrounding you in a lasting radiant warmth.
