Light, warm down jacket shines as an alpine midlayer and versatile standalone. *The Cerium Jacket was previously the Cerium LT Jacket.
CERIUM
Streamlined, minimalist and lightweight technical down insulation. High warmth to weight ratio.
ESSENTIALS
Versatile high performance designs for diverse activities and conditions.
DOWN INSULATION
Highly efficient natural insulation that compacts well and offers excellent warmth to weight.
CERIUM JACKET
Proven across a range of alpine missions and backcountry adventures, the Cerium packs small, weighs little, and delivers big warmth. The design – refined for optimal fit and efficiency – utilizes more sustainable materials while delivering the same outstanding warmth-to-weight ratio. Responsibly-sourced 850 fill down – with Coreloft™ synthetic utilized in areas prone to moisture – provides premium insulation. The recycled 15D Arato™ nylon outer is light and durable, the bio-derived liner reduces petroleum use, and the streamlined design is articulated for freedom of movement. Redesigned with a reverse coil front zipper and TPU pulls for a cleaner profile and improved durability. (The Cerium Jacket was previously the Cerium LT Jacket.)
