The Pacaya Insulated Jacket does a little of everything. Shell and insulating layer in one, it relies on a blend of Polartec® Alpha® and Polartec® Power Stretch® insulations to help regulate body temperature and ensure unrestricted movement. This blend of active insulations makes the Pacaya a great midlayer for skiing, standalone jacket for fall and spring hiking, or light around-town jacket. Additionally, the 20D nylon shell is treated with a DWR finish to add a little more protection from light precipitation. The hoodless version keeps things streamlined while layering, and the tall collar keeps your neck protected from the elements.
