Whether you're navigating alpine routes or layering for everyday adventures, the Arc'teryx Cerium Jacket delivers championship-level warmth without the weight penalty. This technical powerhouse uses innovative Down Composite Mapping™ technology to strategically place 850-fill European white goose down where you need maximum warmth, while synthetic Coreloft™ insulation guards moisture-prone zones like shoulders and cuffs. At just 10.6 oz, this incredibly packable jacket disappears into its included stuff sack when not needed, yet provides serious insulation when the temperature drops. The fitted profile slides seamlessly under your shell jacket or over base layers, while the recycled Arato™ nylon shell shrugs off wind and light moisture. From multi-pitch routes to winter commutes, the Cerium proves that you don't need to choose between packability and performance – you can have both in one expertly engineered piece that's ready for whatever your next adventure throws at you.
