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.

Size & Fit: 

The trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over the first layers or under the outer layers.
