The Altitude Down Parka is a classic expedition-warmth parka with a modern design. This heavy hitting mid-to-outer layer was designed to keep you warm during passive activities in extreme cold. A Pertex® Quantum ripstop nylon shell holds roughly 8oz of RDS certified 850 fill-power HyperDry™ Down for ultimate warmth in a lightweight package.
