The KUHL AeroLight is a lightweight synthetic-insulated jacket built as a midlayer for active cold-weather use. Its KUHL AIR nylon shell is stretchy and breathable, and knit underarm gussets vent heat when you move hard. It suits hikers, skiers and runners who want warmth without bulk under a shell. Against heavier puffy midlayers it trades some warmth for mobility and breathability, and the athletic cut runs trim, so sizing up is common.

Owners rate it well as a breathable active midlayer, praising stretch and comfort on the move. The main complaints are the snug athletic fit and modest warmth for very cold days.
