Whether you know it or not, pumping your arms is a huge part of running — so you need a workout shirt that wont hold you back or restrict your motion. Thats where the Zoot Run Moonlight Racerback tank comes in. The racerback-style cut allows maximum range of motion for your arms, and a streamlined fit combined with lightweight, moisture-wicking fabric ensures you wont be weighed down no matter how hard you sweat. Power mesh panels provide enhanced support and breathability, so youll feel secure and comfortable whether youre heading out for a light jog or an endurance run. With reflective details and UPF 50+, youll be protected during both daytime and nighttime runs. The best part: a built-in bra with stash pocket holds your essentials while on the go.
