Water that tastes good, goes down good. Made with taste-free TPU, the HydraFlex drink tube is designed to keep your water tasting fresh. And because it's non-kinking, you receive a steady flow every single time. This very flexible, non-kinking drink tube provides a steady flow of water. The hose is approximately 91.5 cm / 35 inches long. The High-flow Blaster bite valve provides a great flow and self seals after each sip and features a twist on/off feature to prevent leaks when not in use. The hose is safe, reliable and 100% BPA and PVC-free. The hose is made out of TPU, PP / POM and silicone and is approximately 6 mm / 1/4 inch in diameter. The hose comes with a Plug-N-Play connector.
