Strategically placed stretch, mesh panels along shoulders, back, and sides provide you the breathability and mobility a runner needs. Flatlock seams reduce chafing and increase comfort, and modified princess seamlines give you a flattering fit. 50+UPF protects you from harmful rays during the day, while reflective details increase your visibility if running in low-light conditions.
