FOX40 Classic CMG whistle included.

The Fox 40 Protective Pouch is designed to protect the user and others in close vicinity from droplets while still maximizing sound power. Manufactured using 100% moisture resistant polyester fabric to seal around the Cushioned Mouth Grip of your Fox 40 whistle so it will not block the chambers. The Pouch is best used with a Fox 40 Classic CMG or Fox 40 Fuziun: Reducing output by only 1.5 dB, which is hard to detect by the human ear. Comes with an elastic loop to connect your lanyard and can also be used handheld.
