The Mountain Hardwear Women's Nitrous Hooded Down Parka is a low profile hooded jacket with an outstanding warmth to weight ratio, thanks to the Q.Shield DOWN 800 fill insulation, which retains critical loft and warmth even when wet. It's lightweight and easy to pack, but performs like a much more serious and substantial jacket. Body shell fabric is Sensor ripstop 100% polyester. Q Shield down 800 fill insulation repels moisture. Longer hem length provides extra warmth and coverage. Insulated, two way adjustable hood for easy fit customization. Two zippered hand warmer pockets. Standard fit is not too tight, not too loose. Fits over base and mid layers without restricting movement. Center back length: 35 89 cm. Avg. wt. 13 oz. 377 g.
