Whether it's race day or a training day, the Base Running Singlet from Miler is the elite choice for serious runners and weekend warriors alike. Our Head of Product at Future Proper swears by this tank, and we tend to think he's got a point. When you're deep in the pain cave on mile ten, the combination of no chafe bonded seams and lux mesh fabric are a godsend. Miler makes their singlet in New York City from a lightweight, breathable Swiss-made technical fabric. Pro tip: pair the Base Running Singlet with Miler's Base Running Short and be a legend.
