Arc’teryx Atom Ar S

All-Around Performance.The men's Atom AR jacket is suitable for seasonal standalone use while doubling as a warmer mid layer during winter activities. Hydrophobic, compactable, and resilient 120g Coreloft insulation pads the core. The underarms and shoulders use 80 and 60g Coreloft fillings. Body-mapped insulation captures an abundant amount of body heat while packing small. The soft, light abrasion-resistant Tyono 30 shell has a water-repellent finish. The athletic fit is complemented by targeted articulation, improving its mobility for ski missions and frosty day hikes. The jacket comes with a full front zipper and a corded puller, and when done-up secures the chin guard and lightly insulated collar. A breeze-blocking wind flap backs the front zipper. The stretch-knit sleeve cuffs are woven for a snug fit around wrists and over gloves. The jacket's drop-back hem is laminated and can be adjusted with a drawcord while providing lower rear coverage.
