The RSG Combat Singlet is a blue race singlet featuring a printed RSG logo on the front and label on the back. The singlet is moisture-wicking and quick-drying, which ensures high breathability and increased airflow. The technical construction reduces the fabric’s ability to cling to your skin. It is made from recycled polyester, which is a high-performance lightweight material offering high flexibility. RSG stands for 'Running Shoe Geek', which is an online running community.
