High-performance outerwear company NuDown is ready to provide its customers the facility of adjusting the level of warmth provided by their outerwear garment, with a line of vests and jackets for men and women which uses compressed air for insulation. Using a pocketsize hand pump, the wearers can pump air into the dynamic chambers in the garment to provide required warmth or hit a release valve for instant cooling, with a temperature variation range of 40 degrees. Including Mount Tallac, Squaw Peak Jacket, and Mount Whitney Vest, the fall 2015 collection comprises six premium high-tech outerwear styles.
