As a mid layer or standalone piece in cool, dry conditions, the Cerium LT Jacket offers exceptional warmth for little weight. Premium 850 fill down is resilient and warm, the Arato™ 10 shell provides lightweight durability, and Down Composite Mapping™ strategically places Coreloft™ synthetic insulation in moisture-prone areas. The women’s specific trim fit with articulated construction moves with the body, and the sewn-through construction further reduces weight and increases packability.
