For warmth and comfort in sub-zero conditions, this thermal vest is insulated with our proprietary Mammut LOOPINSULATION, a 100% recycled filling made from 50% industrial rope production offcuts & 50% rPET. Combined with a recycled wind- and water-repellent outer fabric, this cozy layer offers the protection you need and marks an important step towards reducing the use of virgin resources and supporting a more circular economy. The design and solid colors of our Corporate Crag IN Vest allow company logos to be positioned where desired.
