Made of jersey-knit 100% polyester fabric, the Performance Polo is wrinkle and shrink-resistant, snag-resistant, anti-odor, and has a stay-flat, no-roll collar. You could wad this thing up, stuff it in a cannon, and fire it down the range, and it would still look shiny and new. The Performance Polo also features collarbone and front mic-clip pockets, embellishment friendly pen pocket, and it wicks moisture.
