Pro Cool Compression is a new baselayer from Nike, that sits tight on the body, provides good support - to give you the ability to perform.
The shirt is made from Nike's well known Dri-FIT material, that keeps sweat from the body - to keep you dry and comfortable. Furthermore it has large panels of mesh, under the armpits and on the back to increase breathability. When you train hard, the back is where you sweat the most. Nike has therefore designed a special mesh zone on to ensure airflow on the back.
The Dri-FIT material is able to flex in all directions. This provides a tighter fit, to give you the freedom to move and ensure the fit all the time.
Pro Cool Compression is designed with a compression fit, meaning that the shirt is locked on you when you put it on. It sits tit on you, feeling like an extra layer of skin.
Made from 90% polyester and 10% spandex.
