A cold-weather bag with a trim, efficient cut to please alpinists, expedition climbers and skiers out on extended tours. It's light, very compact and capitalizes on the modern tech of hydrophobic down, reflective lining, and an engineered toe pocket that traps heat around your feet. Designed with input from polar explorer Eric Larson, it incorporates expedition-worthy features like a snorkel hood, central zip and overlapping side vents.
