Worn as a midlayer or standalone, the Cerium has emerged as a go-to for virtually any alpine undertaking. Seeking to take it higher, we refined the design and sourced more sustainable materials while maintaining its exceptional warmth-to-weight ratio and packability. Responsibly-sourced 850 fill down – with Coreloft synthetic utilized in areas prone to moisture – provides premium insulation. The outer – recycled 15D Arato nylon – is light and durable, a bio-derived liner reduces petroleum use, and the insulated StormHood extends the warmth.

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 our first layers. This model's fit has evolved. Before you check out, please make sure to reference our sizing chart to determine your correct size.
