A thicker yet breathable running top for cooler season runs and workouts. The Fly By 1/2 Zip's semi-fitted design is great for layering, as it's not too light or too heavy, and lets you move freely.
- DriLayer® polyester adds warmth for cold-weather activities and wicks moisture to keep you dry and comfortable
- Half zip lets you increase venting when activity levels heat up
- Semi-fitted design lets you wear it as an outer layer on cool days or as a mid-layer on cold days
