A warm down vest – it’s a winter necessity. Born from an alpine-proven design, refined to perform as a versatile standalone, the Thorium is the one you reach for before stepping out into the cold. The 750 fill-power Responsible Down Standard certified grey goose down delivers excellent warmth for its weight. Down Composite Mapping™ strategically places Coreloft™ synthetic insulation in areas prone to moisture, the bio-derived liner reduces petroleum use, and the light, durable Arato™ 30 nylon shell has a DWR treatment for water repellency.

Size and Fit Tips: Regular Fit - Our classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably over our first layers. Be sure to double-check our new sizing charts before checkout.
