RB is excited to introduce the latest in performance mask technology – the Performance X. The X series is an even lighter version of our original performance mask made for high output activities and reduces the thermal burden of traditional designs. Rated the best lightweight mask by Runner's World magazine!
Consisting of two layers of durable knit performance fabric, the internal fabric includes a pocket slit where an additional PM2.5 filter may be added for additional protection. 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.
Please note that this is a non-medical grade mask and does not meet OSHA standards for PPE (Personal Protective equipment).
One Size Fits Most. Wash, Dry, and Re-Use.
This is a Non-Returnable/Non-Refundable item for obvious health and safety reasons.
