Granite II Jacket - Reversible


The Granite is not just another puffy. It’s a lightweight technical piece that keeps you comfortable in a wide range of conditions. The Granite has 37.5® sixty-gram insulation which retains body heat, while 37.5 active particles embedded in the insulation accelerate vapor movement and prevent overheating and moisture build-up. Further, 37.5 technology is sustainable and never washes out or gets tired.

37.5® technology removes moisture before it turns into sweat, helping you maintain an ideal core temperature so that you can perform your best. Climate control clothing with 37.5® Technology has been proven to decrease the rate of core temperature buildup, increasing athletic performance by up to 26%. Whether you’re training, competing, or recovering, your performance depends on staying in your comfort zone as long as possible.
