Men's Seamless Merino LS Zip

Next-to-skin base layers are the hardest working gear in your entire system. Hydrophilic (Wool) and Hydrophobic (Poly) interact with your body’s natural heat and activity. Designed to move moisture off your skin and into a mid-layer (or the air) during exertion, and trap dry air when you stop. The seamless construction is body-mapped throughout. A jersey knit on the chest for smooth structure and comfort, ribbed shoulders and sleeves for contoured mobility, and mesh on the underarms and back where airflow allows higher performance and comfort.
