Sports Mask Valves

Impressed

Work surprisingly well. Simplicity, functional, effective but on first outing while removing my scarf one valve popped open and the diaphragm fell out. My order for replacement was filled promptly and I'm more vigilant now that I'm aware it can happen. Maybe offer replacement diaphragms.

Face Mask Comfort

These masks are very comfortable both from a breathable and comfort standpoint. The valves are easy to lose. I suggest getting extras.
