A breathable running top for shoulder season runs or cooler workouts. The semi-fitted design is great for layering, as it's not too light or too heavy, and lets you move freely. Breathable DryLayer polyester and spandex wicks moisture and stretches for easy movement. Half zip with chin guard lets you customize the venting. Drop-in pocket at rear right holds small items. Thumbholes keep sleeves in place when the intensity ramps up.
