This polo from Sport-Tek has ventilation panels of an ultra-dry mesh technology that help to create a cool and breathable polo. There are also stretch gussets that add extra mobility. The body is 100% mini pique and the insets are 94/6 poly/spandex stretch mesh. On a personal note - this is the polo used by our staff when we worked at the football stadium. I can vouch that it is a quality polo that does help you keep your cool. This version is decorated with an embroidered interlocking NC.
