Stay warm without sacrificing mobility in the Arc’teryx Atom Jacket—your ultimate synthetic insulated jacket for dynamic adventures and daily life. Previously known as the Atom LT, this refined icon delivers reliable warmth whether you’re tackling backcountry hikes, alpine ascents, or bustling city commutes. Why choose between layers? Its versatile design excels as both a breathable midlayer under shells and a standalone piece when conditions ease.
Featuring Coreloft™ Compact 60 synthetic insulation, it retains heat even when damp and springs back after constant packing—perfect for travelers seeking a packable synthetic insulation jacket for hiking. The durable Tyono™ 20 face fabric shields against wind and light precipitation, while stretch fleece side panels boost ventilation and freedom during high-output activities. Plus, dope-dyed fabric reduces water use and CO₂ emissions without fading, making it a smarter choice for eco-conscious explorers.
Ideal for unpredictable mountain weather or crisp downtown mornings, this durable commuter layer balances weather resistance with next-to-skin comfort. Experience trusted performance that adapts from trailhead to town—no more juggling bulky gear. Lightweight, resilient, and thoughtfully engineered for real-world versatility, the Atom Jacket keeps you moving confidently through every season.
