Cerium jacket

Exceptionally lightweight and warm, the Cerium Jacket is the ideal insulation for backcountry minimalists. Easily stowed in your pack, it's instantly available for core warmth as a mid-layer in cold, dry conditions or as standalone insulation during breaks or at camp. Responsibly sourced 850-fill down—with synthetic Coreloft™ used in moisture-prone areas—provides premium insulation. A bio-derived lining helps reduce petroleum use, and the recycled 15D Arato™ nylon shell is lightweight and durable. A stuff sack is included for compact transport.
