Mammut

Broad Peak II Down Jacket - Men's

When you're hunkered down at basecamp, you need gear that packs down about that small but will provide lots of warmth, like the Mammut Men's Broad Peak II Down Jacket. You can't beat it on a blustery night, because the 750-fill power goose down is super warm. Keep wearing it when you are making coffee in the morning and the Pertex Microlight shell can shed snow and water if the clouds start to drip. Then the weather breaks, and it's time to go, so you pack up the minimalist jacket in your pack without taking up too much space, because it weights only 11oz and stows inside its left hand pocket.
