Introducing the Eos. Named for the goddess of the dawn, the Eos jacket is designed for early morning starts that call for an extra layer of no-fuss insulation. With just the right amount of premium 900 fill down, this hooded down sweater excels at keeping you warm on its own when conditions call for moving light and fast, or as a layering piece when weather moves in. Equally at home on the trail or around town, this lightweight and packable jacket will do wonders in the outerwear quiver.
