Oiselle's beloved Lux Layer reimagined and slightly updated in even softer Lux fabric. It's one of their original long sleeve tops, and a best seller, loved for its killer combo of softness and durability. It's the running top that goes forever, through hard miles and hard washes, and never lets up. In addition to fitted but not tight sleeves, and thumb holes, the neckline is a gentle scoop. Hello clavicle, we love you.
