The Womens Arcteryx Cerium LT Jacket is one of the lightest jackets in Arcteryx Mountain Essentials collection. Arc’teryx designed the Cerium LT Jacket to function as a warm mid-layer when paired with your favorite jacket or as your outer layer on milder days. 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. Low profile elasticized cuffs offers easy layering and the Cerium even comes with a stuff sack for easy storage. The Womens Arcteryx Cerium LT Jacket delivers insulated warmth in a lightweight package and revolutionized design that will be a favorite for years to come.
