An optimally balanced personal climate is hard to maintain in the winter. It can get very cold on the ski lift then way too warm on the descent. X-BIONIC® INVENT precisely supports your body’s temperature regulation. The three-dimensional knit structure can hold an insulating layer of air on the body. In the activity phase, excess warmth can be dissipated quickly via the Air-Conditioning Channel® and the AirConditioningSpots.
