Wearing a face covering in public is a damn good idea. Exercising outside is great for both physical and mental health. Unfortunately, most masks are far from ideal for running and training. That's why Under Armour created its Sportsmask. The multi-layer build uses a structured design to sit above the face and includes a water-resistant outer shell, anti-microbial treatment on the inside layer, polyurethane open-cell foam in the middle that lets air, but not moisture, through, and UA Iso-Chill fabric on interior lining & earloops for all-day comfort. Available in four sizes to fit a wide variety of faces.
