Weighing a scant 170 grams and packing smaller than a grapefruit, the Cerium Vest performs as a minimalist’s alpine midlayer or standalone in cool, dry conditions. Responsibly-sourced 850 fill down – with Coreloft™ synthetic utilized in areas prone to moisture – provides premium insulation. A bio-derived liner reduces petroleum use, and the recycled 15D Arato™ nylon outer is light and durable. Streamlined in its design, it layers comfortably under a shell and easily fits into its included stuff sack for compact transport.

The Cerium Vest was previously the Cerium LT Vest.

Fit

• Fitted Fit: This 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 first layers.
