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.
