The Arc'teryx Atom LT Jacket is super light, breathable, and warm. It's not hard to see why the Atom remains one of the best-selling and highest-rated midlayers year after year, beloved by skiers, hikers, climbers, and travelers alike. It's great on its own for a bit of warmth when the weather is cool and mild. The versatility to do more comes from an air permeable Tyono shell and Coreloft insulation that really shine when used to add warmth under a shell without putting a stop to airflow or breathability.
