Wool liners are always in demand, and the Merino 150 Sensor Liners address and fulfill those expectations with a couple of added bonuses. Naturally odor resistant, breathable, and wicking, all-natural Interlock Merino Wool retains just enough warmth for cool activities, but doesn't hold onto the sweat and smells like other fabrics. Touchscreen compatible and sporting a tapered wrist, these wool liners will stay on all day - to help you stay out all day.
