Cerium Vest M

The Cerium Vest M from Arc'teryx is lightweight and packs down small, but keeps you exceptionally warm for its low weight with European white goose down. In exposed areas, like the shoulders, the down is supported by a moisture-insensitive recycled polyester fill. The recycled polyamide outer fabric keeps the down and synthetic fibers in, and the water repellent waterproofing keeps moisture out. The Cerium Vest is cut for ease of movement and close to the body to fit another layer over it, and has three zippered pockets.
