Big Flipper sports cap made from BPA free, non leaching polypropylene. Great cap for adults delivering maximum waterflow. Easy to use & easy to clean. Our market research testers loved this cap ‘Fabulous, our favourite cap. Great for big glugs of water when you need it’. We cannot guarantee that this cap will be free from leaks as it is designed to be a stand up, easy to open, type of cap.
NOTE: This cap design has a flip down/flip up lid. If the bottle is in a bag where it may be accidentally opened by other items you may wish to opt for a screw in loop cap or flat cap or a supergreen sports cap. BPA free polypropylene is more brittle than other plastics so please take care with this cap
