Climb the alpine and ski the backcountry with the Marmot Women's Megawatt Down Jacket. Light and lofty 800 fill down insulation warms the core and hood, while Polartec's air permeable Alpha insulates the sleeves for better breathability. Featherweight Pertex Quantum wraps up this innovative insulation for windproof protection, abrasion resistance, and downproof durability. Marmot also added an AirExchange lining for the ventilation that sweaty ascents call for. The Pack Pockets are always accessible, even with a backpack or harness on.
