The Mountain Equipment Paiyu Jacket features a dual-layer offset baffle construction, down insulation, and a heat-reflective internal fabric to provide lightweight, packable warmth for our winter mountain expeditions. The exterior DRILITE LOFT fabric construction is highly water-resistant, windproof, and offers unmatched protection without sacrificing breathability, while the 700-fill power duck-down insulation provides the warmth necessary to stay comfortable in frigid temperatures without adding bulk. For extended coverage, the Mountain HC hood provides insulation and is fully adjustable to keep out the cold, while a variety of pockets provide ample storage to keep our most-used essentials close by.
