The Woolpower Vest 400 is a thick and warm vest for resting at the summit or traveling in colder climes. The material consists of 70 percent finest merino wool mixed with polyamide and elastane. As a result, the vest fits close to the body, is more durable and keeps its shape. The collar is comfortably high and closes nicely. It is produced in Sweden, but has proven itself in the Alps. Please note that the vest is rather large.
