An alpine-ready midlayer in cold conditions, a warming layer during rest phases – the iconic Cerium is made for backcountry missions. Featuring a refined design utilizing more sustainable materials, it delivers outstanding warmth, packs small, and weighs just 255 grams. Responsibly-sourced 850 fill down – with Coreloft™ synthetic used in areas prone to moisture – provides premium insulation. The recycled 15D Arato™ nylon outer is light and durable, a bio-derived liner reduces petroleum use, and the streamlined design is articulated for freedom of movement.
The Cerium Jacket was previously the Cerium LT Jacket.
