Arc'teryx Thorium Hooded Down Jacket

The Arc'teryx Thorium Hooded Down Jacket is a men's insulated layer for cold-weather outings and climbing breaks. It combines 750-fill European grey goose down with Coreloft synthetic insulation and an Arato nylon ripstop shell. A boxier silhouette accommodates layering, while a two-way front zip offers access when wearing a climbing harness. The compressible design makes it convenient to pack as an additional warm layer.

Cold-Weather Layering

Pull the Thorium over your base and midlayers during a cold outdoor break, then adjust the hood and hem for coverage. Fleece-lined hand pockets add comfort, while the two internal dump pockets provide accessible storage. Choose compatible layers and equipment for the conditions. Moisture resistance is not the same as waterproof protection; use a suitable outer shell when sustained rain is expected.
