Arc'teryxCerium SL Down Jacket - Women's

Warmth without the weight.

Weighing just a tick over five ounces, the Arc'teryx Cerium SL Down Jacket delivers incredible warmth without weighing you down, thanks to its Down Composite Mapping that places down and synthetic insulation where it's needed most. 850-fill European goose down traps heat with its high-loft rating, and strategically placed Coreloft 40 and 100 insulation won't allow its heat-trapping ability to be compromised by ambient moisture and condensation, which are known enemies of down's insulating abilities. The jacket's Thisela 7D ripstop nylon face fabric offers ultra-light weight, while retaining durability through its super-tight weave. Protecting the jacket's down insulation from outside moisture, the face fabric's DWR coating sheds light precipitation when you're getting after it on long hikes and ski tours.

      Is slim fit or regular fit


      This is a "trim" fit by Arc'teryx. Not necessarily a slim fit as its meant for an athletic build.
