Cushioned Mouth Grip (CMG) improves the very first Fox 40 Classic CMG Whistle with Breakaway Lanyard. Ground breaking thermoplastic material provides exceptional grip and protection for your teeth. The Classic CMG is terrific for sports officials, or anyone that must keep the whistle within his or her mouth for a longer time. Law enforcement, firefighters, crisis strategy organizations, school crossing safeguards, security officers and boating enthusiasts all use the Fox 40 Classic CMG Pea-less Whistle due to this function, and to conserve a healthy and safe atmosphere. Designed from impressive thermoplastic, the body is integrated with over-mold CMG technology. Thus, Fox 40 has joined the pea-less whistle and padded mouth grip together in a single model.
