The new mouthpiece is leak-free thanks to its water-stop locking action. Simply turn to open. Light pressure activates the drink opening, which provides a pleasingly high flow of liquid regardless of the position in the mouth. When done drinking, the integral spring valve automatically closes the mouthpiece. The “Hi-Flow Bite Valve” is easily disassembled for cleaning.
The attachable protective cap keeps the mouthpiece free from dirt during longer journeys.
The whole system is BPA-free as well as PFC-free.

This deuter product is free of per- & polyfluorinated chemicals. deuter thus reduces the use of environmentally harmful substances that pollute the environment and health.
PFC is used, among other things, as a coating for rain protection, as they have water-, dirt- and grease-repellent properties.
Instead, deuter now uses DWR (Durable Water Repellency) impregnation that is harmless to health and the environment.
