Arc'teryx Thorium Vest (Women's)
The Arc'teryx Thorium Vest is built for cold, high-output environments where reliable insulation matters. Whether you’re layering up for an alpine start or adding core warmth on a winter hike, this women’s down vest delivers exceptional performance without excess bulk.
Filled with 750 fill-power grey goose down, it provides outstanding warmth-to-weight, while Down Composite Mapping™ places Coreloft™ synthetic insulation in moisture-prone zones to maintain performance in variable conditions. The result is a lightweight insulated vest that stays warm even when the weather shifts.
The durable Arato™ shell with FC0 DWR treatment sheds light moisture, while its breathable, packable design makes it easy to carry and deploy when temperatures drop.
For cold mornings, exposed ridgelines, and travel-ready layering, this is a technical down vest you can rely on when it has to work.
