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.The Cerium Hoody was previously the Cerium LT Hoody.
