A flip-up gap with a fast flow spout to allow for thirst quenching gulps when on-the-go, to fit all bottles in the One Green Bottle range.
A completely leak-proof easy drinking spout, perfect for all age groups. Its fast flow air valve means that you can even pour water from the spout. The wide spout makes it easy to rinse through. Suitable for dishwasher.
Please note: The caps have a small white valve and care must be taken not to lose this valve when cleaning the caps (if lost, the cap won't work). The valve is small and difficult to remove but if you are concerned please do not use for very small children.
