PROTECTS YOUR CRITICAL AREAS. 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 (blue in the illustration). In the activity phase, excess warmth can be dissipated quickly via the AirConditioning Channel® and the AirConditioningSpots™.
