The Thorium Jacket Men's by Arc'teryx focuses on warmth and breathability for outdoor activities in real alpine conditions.
This jacket features hybrid insulation arranged according to Down Composite Mapping™ technology: warm, compressible goose down is placed around the torso and in the sleeves. The synthetic Coreloft™ insulation, highly breathable, is distributed at the cuffs, under the arms and in areas prone to moisture buildup. In addition, the StormHood with synthetic insulation provides extra warmth. The slightly textured Arato™ 30 nylon outer fabric resists abrasion, offers wind resistance and water repellency, enhanced by a DWR finish. 

This functional, clean-styled jacket has three pockets for your personal items. It packs easily into its compression sack for minimal bulk in the bottom of a pack. Exceptionally versatile, the Thorium AR can be worn as a midlayer under a protective shell or alone in cold, dry conditions.
