The performance polo is made from 100% polyester pique mesh striped knit fabric that features Opti-Dri technology, providing maximum breathability that transfers moisture away from the body to keep you cool and dry. The shirt is completed with a rib knit collar and three-button placket with Callaway embossed buttons.
