Lightweight, breathable, and cut to deliver a comfortable and chafe-free fit, the La Sportiva Men's Velocity Tank Top is a solid choice whether you're running a new trail or your favorite route around town. Its moisture-wicking polyester fabric has just a touch of stretch, while body-mapped venting helps keep a supply of cool air circulating through. La Sportiva even treated the shirt with a Polygiene anti-odor finish to combat post-run funk.
