SUN MOUNTAIN Men's Colter Full Zip Insulated Jacket

In the Colter Jacket we are using patented 37.5® premium insulation, which makes you more comfortable by helping control your core temperature. The insulation retains body heat, while 37.5 active particles embedded in the insulation accelerate vapour movement and prevent overheating and moisture build-up. Strategically placed stretch panels provide freedom of movement. The overall result is a multi-use, comfortable, ultra-lightweight technical piece that is warm, without the bulk.
