Nike Dri-FIT The shirt is made from Nike's Dri-FIT material. The Dri-FIT is a breathable, quick drying lightweight material, which wicks sweat and moisture away from your body, so you are kept dry and comfortable. It works by distributing the sweat and moisture equally around the material and thereby improving the body's natural cooling system. The shirt has mesh stripes which runs along the side. The mesh stripes are elastic and will expand when you are in motion, and this will also allow the airflow to increase.
