Arc'teryx Atom Men's Insulated Jacket

The Arc'teryx Atom Jacket is a synthetic-insulated midlayer built for high-output days across hiking, climbing, and touring. Its Coreloft 60 insulation stays warm even in light weather, making it a strong alternative to down when you are moving fast and working hard.

Stretch fleece side panels add breathability and ventilation, while the Tyono 20 face fabric and FC0 DWR finish shed light moisture. At 335 g in size Medium, it packs down small and layers cleanly under a shell or wears solo on milder days.
