The ASICS RUNNERS FACE COVER was designed at the ASICS Institute of Sport Science (ISS) and helps prevent the spread of droplets by covering the nasal passage without restricting airflow. This face cover’s material helps the fabric dry quickly while improving comfort and breathability. Equipped with more room inside the face cover to make it easier to breathe, this accessory also has strategically placed air holes that increase airflow while preventing saliva from splashing into the open air. Featuring an adjustable fit to accommodate a wide range of runners, this design is also formed with approximately 31% recycled materials for a more sustainable manufacturing approach. Formed with a water repellent exterior, the ASICS RUNNERS FACE COVER is also equipped with a washable fabric that makes it easier to keep clean.
