The Merino base layer is shaped for flexibility and functionality for all sports through winter. Sitting close to your body at all times, the jersey moves naturally with you through a full range of motion.
Features like a mock neck design give warmth and comfort under everything from a ski race suit to warm cycling jersey, with the higher collar line giving warmth without the clumsiness or tightness of having multiple zips at your neck.
The Merino base layer provides effective thermal regulation and wicks moisture away from your skin, keeping you feeling dry and comfortable.
Constructed with as few seams as possible, all seam placements have been carefully thought out so as to ensure maximum comfort against your body. Details like the hanger loop are added to the outside of the jersey so that you do not feel it against your skin.
