Description

The Sport-Tek ST640 PosiCharge RacerMesh Polo Shirt is a lightweight, breathable performance polo built for active wear and clean, professional branding. It is made from a 3.8 ounce 100% polyester flat-back mesh with PosiCharge technology, which locks in color so the polo keeps its look wash after wash and resists the fading that can dull team colors over a season. The airy mesh construction and moisture-wicking finish make the ST640 a strong choice for teams, coaches, golf programs, and everyday active wear.

The construction pairs performance with a sharp, clean look. Moisture-wicking properties pull sweat away to keep you dry and comfortable through a warm day, and the flat back mesh moves air while sitting smoothly against the skin. A flat knit collar keeps the neckline neat, and a taped neck reinforces it for lasting structure. A three-button placket with dyed-to-match buttons gives it a tidy, cohesive front, and set-in, open-hem sleeves add a comfortable shoulder line with a relaxed finish. A tag-free label keeps the interior comfortable, ready for your logo.
