Cerium jacket

Weighing just a few grams and smaller than a grapefruit, the Cerium Jacket is a minimalist alpine midlayer or standalone in cool, dry conditions. Responsibly sourced 850-fill down—with synthetic Coreloft™ used in moisture-prone areas—provides premium insulation, and the recycled 15D Arato™ nylon shell is lightweight and durable. Its streamlined design layers comfortably under a shell and packs easily into its included stuff sack for compact transport.
