Arc'teryx Thorium Vest Women's

A warm down vest for winter layering, combining dependable core insulation with a light, durable shell.

The women’s Thorium Vest uses 750 fill-power, RDS-certified goose down for efficient warmth without the bulk of a full jacket. Down Composite Mapping places Coreloft synthetic insulation in moisture-prone areas to help maintain performance during changing conditions.

The Arato 30 nylon shell is lightweight and durable, with a water-repellent treatment for light moisture. Zippered hand pockets and an internal security pocket keep essentials accessible, making the vest useful as a standalone layer or beneath a protective shell.
