BOCO Gear is proud to offer a new style of face mask – the performance X (for exercise) mask. An updated, lighter version of the original BOCO Face Mask, the X mask is made for performance and high output activities. Consisting of two layers of durable knit performance fabric, the internal layer features a slit that can hold a filter for additional protection. The soft elastic is sewn to both the top and bottom of the mask for a secure fit over the ears. These masks cover the mouth and nose comfortably.
