MontBell

Ultralight Down Parka - Women's

At just over eight ounces, the Montbell Women's Ultralight Down Parka weighs less than a can of soda and brings the core-stoking warmth of 800-fill goose down to your winter life. This highly compressible jacket packs down to the size of your water bottle to easily to slide inside your hiking, climbing, or carry-on bag, and reinflates faster than most celebrity chef egos. The body-slimming silhouette lets you slink between trees or to the front of the tram line without leaving a wake of of bodies behind you.

The entire jacket, hood included, tips the scales just over eight ounces. The 800-fill down is responsible for a solid two ounces, or a quarter of the weight. The high fill-power down means for two ounces of insulation, you get a bigger bang for your insulation buck than a lower fill-power down could provide. The fill-power indicates how much space a single ounce of down occupies. The bigger the number, the more space that ounce of down takes up. The more space consumed by the down, the more warmth the insulation provides per unit of weight. Here, you get a full two ounces of 800-fill power down. For you, this just means an eerie amount of warmth for a jacket that seems to float.

The hem drawcords hide in the pocket so you don't have to expose your delicate digits when you want to seal out cold air. The insulated hood won't let you lose your head and adjusts for comfortable fit. Sewn-through construction prevents the down from shifting and settling, and zippered hand-warmer pockets should prevent your mid-morning snack from freezing.
