Arc'teryx Cerium Jacket

The Cerium Jacket is a refined, alpine-ready midlayer crafted with responsibly sourced 850 fill European white goose down and Coreloft™ synthetic insulation in moisture-prone areas. The recycled 15D Arato™ nylon shell is featherlight, durable, and finished with a PFAS-free DWR, while the bio-derived lining adds a sustainable touch. This combination delivers an exceptional warmth-to-weight ratio and packs down small, making it an effortless companion for cold-weather missions.
