Arc'teryx Thorium Jacket Women's

When the temperature drops and you still want to be outside, the Thorium Jacket is the layer you reach for. Filled with responsibly-sourced 750 fill-power grey goose down and finished with a lightweight, abrasion-resistant Arato nylon shell, it delivers real warmth without weighing you down or bulking up your kit. Down Composite Mapping places synthetic Coreloft insulation exactly where moisture tends to build up, so the jacket keeps performing even when things get damp, while a DWR finish helps shed light rain and snow. The adjustable StormHood tucks in close for extra protection, articulated patterning lets you move freely on the trail or around town, and it packs into its own stuff sack when the sun comes out. Whether you're layering up for a winter hike, standing around camp, or just fighting off an Ottawa cold snap, the Thorium is built to be your go-to.
