To transition from the heat of hiking to the chill of a ridge top wind in comfort, you need garments that work with your body to regulate heat. There are two approaches to this: adapt by proper layering, the second: develop products that regulate heat on their own, so by working with the world leader in insulation, 3M™ Thinsulate™ that’s exactly what we did.
