Designed for those high mountain objectives, the American Mountain Co. Gentlemen's High Altitude Hardshell Jacket was built right here in the USA. This rugged jacket features a robust face fabric, backed by a Schoeller c change membrane for waterproof, breathable performance. Fully taped seams wall out moisture, and the 3xDry moisture management lining helps wick moisture away from your body when you're pushing yourself higher up the mountain. This jacket's well conceived construction includes a helmet compatible hood, underarm ventilation zippers, and harness and backpack compatible front pockets. Aquazip zippers throughout the jacket prevent moisture from leaking through the jacket's most vulnerable points, and an internal zippered pocket keeps valuables secure whether you're mountaineering or enjoying an afternoon snowshoe in the home range.
