The quintessential lightweight, active insulation, down jacket. Everyone needs one, so you might as well buy the best. You will be amazed by how light this jacket is (15 oz) and how warm it will keep you. We packed it with water-repellent goose down, allowing it to retain its loft in wet conditions. We have added 4-way stretch to all the right areas so it will fit close to your body but never constrict your freedom of movement. This hooded jacket also uses CANIS BTL Down Construction featuring no exposed quilting lines and each chamber is individually cut and sewn. To top it all off, the jacket packs down into a waterproof sack perfect for tossing in your pack when its not needed.
