From trail days to rest days, the AirFleece layers right in. With a uniquely airy, stretchy, and plush grid pattern, this quick-drying fleece perfectly balances lightweight warmth, comfort, and breathability. Checkerboard grooves optimize airflow, trap heat, and reduce bulk for active pursuits that start chilly, end toasted, and cover a whole lot of ground in between. With a slimmer, athletic fit designed to layer comfortably under a shell, helmet, or pack, the AirFleece will be your new go-to midlayer across seasons, sports, and terrain—and a favorite even on your off-days.
