A warm down vest for women, the Thorium delivers on winter necessity. Born from an alpine-proven design, it's a versatile standalone piece for stepping into the cold. The vest features 750 fill-power Responsible Down Standard certified grey goose down for excellent warmth, while Down Composite Mapping strategically places Coreloft synthetic insulation in moisture-prone areas to maintain performance even when damp. A bio-derived liner reduces petroleum use, and the light, durable Arato 30 nylon shell carries a DWR treatment for water repellency. The Thorium is suitable for variable-condition use, layering under a shell, and commuting. It's available in black II and comes in sizes XS to XL.
