Arcteryx Nuclei Vest

Windproof Coreloft™ insulated vest providing core warmth for a range of pursuits. Worn as a winter midlayer or a standalone to cut the chill on summer nights at camp, the all-season, all-mountain Nuclei delivers core warmth and windproof protection.

Packable, breathable recycled Coreloft™ insulates. The Arato™ shell is light, durable, and blocks wind, and the liner minimizes airflow to seal in warmth. The streamlined fit and ergonomic patterning keep it comfortable under a shell, and the materials and minimalist design create a compact, lightweight package that fits easily in your pack.
