Known for its natural wicking and thermal regulation, the Merino Wool Base Layer will keep you cool in the heat and warm in the cold. Buttery soft and amazingly comfortable, our 100% New Zealand Merino Wool base layer has high strength-to-weight ratios, and elasticity, plus odor control and wicking properties that are nothing short of amazing. We enhanced Merino base layer even more by adding Polygiene StayFresh and Polygiene OdorCrunch to keep you and your base layer smelling fresher, longer. | Pnuma Outdoors Merino Wool Base Layer Pullover in Camo | Size Small
