Winter climbing midlayer, standalone at camp, packable warmth for backcountry rest periods – the Cerium is alpine proven. Driven by our obsessive attention to detail, we refined the design, sourced sustainable materials, and kept its exceptional warmth-to-weight ratio.

The outer – recycled 15D Arato™ nylon – is light and durable, a bio-derived liner reduces petroleum use, and an insulated StormHood™ extends protection.
