Inspired by our athletes with a thirst for lighter, faster-climbing gear, the Summit FUTURELIGHT(TM) AMK Jacket harnesses NANOREFLECT(TM) and our breathable-waterproof technology. We&';ve added lightweight fabric in the side panels for air permeability and comfort, while articulated patterning mimics the shape of the body, providing a more mobile and flexible fit. Plus, all seams are fully sealed to provide a barrier against wind, rain and snow.
