Cerium Jacket Women's

Lightweight, warm, versatile down jacket
Cerium Jacket Women's
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 and sustainable materials, it delivers outstanding warmth, packs small, and is feather light. 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, and the streamlined design is articulated for freedom of movement.
As an alternative to down fill insulation, we also offer synthetic fill products, such as the Atom Jacket.

We use stitch counts as high as 19 per linear inch — twice the industry standard — to add strength while maintaining mobility and comfort.
