The ASICS GEL-COOL POLO Men wore a thin, high-performance polo shirt with Gel-Cool technology that allows the body to stay cooler and the fabric to dry up quickly. The shirt uses a water-pushing process at the bottom of the back so that the polo shirt can remain light and free of sweat during an active game. Parts of the back, sleeves and shoulders are of a sieve material that provides air permeability and body breathing.
