Arc'teryx Atom LT Hoody

Available at arcteryx.com, REI, Backcountry. The 'Atom LT' is the lighter version; 'Atom AR' is warmer.

Arc'teryx Atom LT Hoody is the technical mid-layer travel jacket. Synthetic Coreloft insulation (warm even when wet), breathable side panels, stretchy fleece under arms, premium build. As a midlayer for mountain or cold-climate travel, it's the standard recommendation. Not packable like Houdini — better as a worn-during-travel layer.
