Arc'teryx Men's Cerium Jacket - Winter 2026/2027

Light, warm down jacket shines as an alpine midlayer and versatile standalone. Proven across a range of alpine missions and backcountry adventures, the Cerium packs small, weighs little, and delivers big warmth. The design - refined for optimal fit and efficiency - utilizes more sustainable materials while delivering the same outstanding warmth-to-weight ratio. Responsibly-sourced 850 fill down - with Coreloft(TM) synthetic utilized in areas prone to moisture - provides premium insulation. The recycled 15D Arato(TM) nylon outer is light and durable, the bio-derived liner reduces petroleum use, and the streamlined design is articulated for freedom of movement.
