"What Our Gearhead® Experts Are Saying:""I wore the Triac Neo Shell Jacket through a full race season, and the Polartec Neo-Shell construction handled everything from calm, cold mornings to windy, exposed sections without ever feeling clammy or restrictive. The articulated sleeves and slim fit work together so well that after the first kilometer I genuinely forgot I was wearing a jacket at all.""When the conditions are hard and the effort is high, the gear you wear either keeps up or gets in the way. The Swix Triac Neo Shell Jacket was built to keep up, constructed from Polartec Neo-Shell in a 3-layer softshell configuration that is fully windproof and highly breathable, managing the intense heat output of serious Nordic skiing without trapping moisture or restricting movement. The slim fit and articulated sleeves follow the body through every stride and pole plant, and reflective details keep you visible when the light is low, and the trails are still yours. A chin guard with storm placket closes out wind at the collar, where it tends to sneak in on fast descents, and YKK zippers ensure reliable performance in the cold conditions where lesser hardware tends to fail. At 320 grams, this is a serious performance jacket that carries almost nothing on the body, leaving everything available for the effort ahead."
