Excellent condition, measures 13” across the chest. I usually wear a medium and it fits me. “More is more when it comes to hidden pockets. And why have one pocket, when you can have three? This design provides plenty of coverage, and run-ready support, with a wide, stable chestband. And when it comes to pockets, you can choose the large center front pocket, with a double layer of Plya™ Interlock, or two small side mesh pockets that are ideal for smaller items such as card keys or lip balm. In the rear, a wide racerback panel is given even more support via two outside straps that help stabilize and disperse pressure.”
