This novel mouthpiece is engineered to quench your thirst with a generous flow of water that won’t dribble all over your shirt. The bite-type mouthpiece has a shutoff valve to prevent wasteful and potentially embarrassing leaking.
- Made of silicone and plastic with a metal spring.
- Integral spring mechanism allows an exceptionally high flow rate and will keep its sealing characteristics after repeated use.
