O2 ESSENTIAL RUNNING SHIRT

Ideal for any runner looking for a highly breathable, moisture-wicking and lightweight short-sleeve option. The COOLMAX ® fiber is a high tech fabric specifically and uniquely engineered to keep you dry, light and comfortable during the whole race or workout

Coolmax® fabrics are made from specially engineered polyester fibers with an increased surface area. This special six-channel fiber forms a transport system that pulls moisture away from the skin to the outer layer of the fabric. It then dries that moisture faster than other fabrics to thermoregulate the body by evaporative cooling
