Ski mid layers

Ski mid layers provide the core insulation of a layering system, and they’re the piece that skiers adjust most as conditions change. The best ones hold heat on a chairlift and release it while moving, before sweat builds up under the shell. We lean toward open-knit fleece and lofted wool, which breathe as they insulate, and opt for light down on colder days. We look for a cut that leaves the arms free and fits beneath a shell without crowding the shoulders.
