Protection from the cold during winter sports. We designed the icy water jacket as a functional insulation layer for ambitious outdoor activities. It can be worn on its own as an outer layer or docked with any compatible weatherproof shell jacket via the system zip. The robust micro Guard max loft synthetic insulation provides reliable protection from the cold and good wicking performance, which is a big advantage when you sweat. When the jacket is worn on its own, the outer fabric shuts out the wind.
