At a cold trailhead, the Micro-Elite Chamois Ankle Tight pulls on as midweight thermal tights with four-way stretch. A gusset eases movement and reduces seam bulk, and a mid-rise waistband holds a hidden key pocket. Moisture transfer fibers carry sweat away from the skin as the climb warms up. What Our Gearhead(R) Experts Are Saying:"I wear these on the coldest chairlift mornings, and the lightly brushed interior holds warmth right against my skin. The smooth outer face stays out of the way of whatever layers go on top."
