The reusable Sport Face Mask is made of high-quality polyester lycra for a soft and comfortable fit. The mask consists of the layers: a water-resistant outter shell, the middle layer is an antimicrobial silver PET filter and the antimicrobial inner layer provides protection from droplets. The face mask for sports feels ultra-soft against the skin and offers an ergonomic, comfortable fit thanks to the stretch lycra band around the head instead of ears. Reusable and washable: Wash these masks in the washing machine at 60 degrees to sanitize for the next wear.
