For training runs or light, fast days outdoors, I'd take a look at this minimalist Osprey run vest. It comes with two Hydraulics 500 mL soft flasks to keep water and calories handy, and the 360-degree stretch mesh gives a stable, bounce-free men's fit, with just enough room for a light layer. This selection is Black, size MD. Visit Osprey for full specifications, current pricing, and availability.
