Tried and tested on numerous alpine missions and adventures, the Arc'teryx Cerium Jacket is lightweight, packable and provides plenty of warmth. The design - reworked for optimal fit and function - uses sustainable materials with a great warmth-to-weight ratio. Responsibly sourced down (850 cuin) combined with synthetic Coreloft in moisture-prone areas provides superior insulation. The outer material - recycled 15D Arato nylon - is lightweight and durable. The bio-sourced lining material reduces the use of petroleum and the insulated StormHood provides reliable protection.
