Welcome to the Obermeyer Off Grid Collection. The Down Shirt is part of the Explorer Series, and is an alpine heritage-inspired down piece that's intended to be worn as a functional standalone for mellow outdoor activities on the mountain. The Explorer Down Shirt uses Allied Feather + Down, fully trackable and sustainably-sourced animal down, which provides best-in-class warmth no matter the conditions. Strategically-placed pockets close this piece out, so go hit the trail and find the joy.
