The P-51 Hygienic Protector Whistle is a 115-decibel pealess sports whistle built for coaches and referees who need volume without the mess. Named as an homage to the classic P-51 fighter plane, it solves a problem every official knows: traditional whistles blast air and spit droplets straight into the faces of nearby players. This one doesn't.

Its patented design redirects airflow and moisture downward instead of forward, cutting droplet spray by more than 95%. Paired with a food-grade silicone mouth grip for comfort and hygiene, it's become a go-to tool for athletic officials who want a cleaner, more considerate way to make the call.
