The Arcteryx Cerium midlayer jacket is engineered for alpine performance, offering lightweight, packable warmth that excels during winter climbing, backcountry rest periods, and as a versatile standalone piece at camp. Designed with precision and sustainability in mind, this technical jacket combines an exceptional warmth-to-weight ratio with responsibly sourced materials. Premium 850-fill down insulation delivers superior warmth, while strategically placed Coreloft synthetic insulation enhances performance in moisture-prone areas. The durable yet ultralight 15D Arato recycled nylon shell ensures long-lasting protection, and a bio-derived liner minimises petroleum use for a reduced environmental footprint. To further shield against harsh mountain conditions, the Cerium features an insulated StormHood, adding reliable coverage and comfort in cold, unpredictable weather.
