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