Tumbling into the snow, popping back up, and heading straight for another lap is a typical run for a kid wearing the Micro-Elite Chamois Crew Top. This midweight youth base layer has a lightly brushed interior that adds warmth without bulk. Moisture Transfer Fibers, which are hydrophobic yarns that move sweat away from the skin, keep the kid dry between laps. What Our Gearhead(R) Experts Are Saying:"My kid wore this under a ski jacket for a full day of falls, and the jacket still zipped without a fight, so the layer never felt bulky. The thumbholes kept the sleeves from riding up whenever the jacket went on or off."
