The Mountain Hardwear Men's Absolute Zero Parka is a climbing parka for high altitude exploration. Atop the highest peaks, you're going to need the warmth this 800 fill power down insulated jacket can provide. Snuggle in and the Q Shield™ Down resists moisture and keeps you toasty. The shell is Dry.Q™ 2L ripstop nylon, which is waterproof and breathable to protect against the snow and sleet you'll come across. Pull on the fixed hood and venture out.
