To help prevent the spread of COVID-19, the CDC recommends people wear a cloth face mask or other covering in public when proper social distancing is difficult to maintain. So Fleet Feet teamed up with BOCO to create a face mask with runners and active lifestyles in mind. BOCO created the mask with two layers of cloth: an outer layer of woven polyester fabric and an inner layer of durable knit performance fabric. Between the layers is an opening for an additional filter. The BOCO face mask uses elastic ear loops to ensure a snug fit, and the generous cut covers your chin, mouth and nose in accordance with CDC recommendations on how to wear a cloth face covering.
