This is the Sparta Prague 2016-18 Away football shirt by Nike.
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. 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.
