Discover why the Arc’teryx Atom Series defines versatile warmth. This lightweight synthetic insulated jacket excels both as a breathable midlayer under shells and a reliable standalone piece for variable conditions—from crisp hikes to urban commutes. Engineered for adventurers who demand adaptability, its Coreloft™ Compact insulation retains heat even when damp and survives constant packing without losing loft.
The durable Tyono™ 20 face fabric shrugs off wind and light precipitation, while stretch fleece side panels enhance mobility and ventilation during high-output activities. Perfect as a hiking midlayer jacket or travel-ready outer layer, it bridges seasons effortlessly.
Noticing the Atom LT evolution? This updated version offers slightly more room through the body for enhanced comfort under layers or solo wear—ideal if you prioritize freedom of movement over a snug fit. Remember: it features a fitted profile designed to layer cleanly over baselayers without bulk. Before ordering, reference our sizing chart—this model’s updated cut ensures precision fit across chest and hips.
Built for relentless use yet packable enough for spontaneous adventures, this weather-resistant synthetic puffy jacket delivers consistent performance where down fails. Whether you’re scrambling peaks or navigating city streets, trust its quick-dry warmth when skies turn gray. A true all-condition essential that earns its place in any kit as your go-to packable insulated pullover.
