The Cerium Puffer Jacket is engineered for cold-weather adventures, featuring a blend of responsibly-sourced 850 fill down and Coreloft™ synthetic insulation for enhanced moisture management. Its lightweight, recycled Arato™ nylon outer repels water and wind, while the adjustable StormHood™ ensures maximum visibility and protection. Ideal for layering, this jacket balances high-performance functionality with sustainable design, making it a versatile choice for climbers and outdoor enthusiasts alike.
From the brand: 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.
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 an insulated StormHood™ extends protection.
