Easy to drink like from a backpack! That was the idea for the development of the AutoClose valve for the new BBB drinking bottles. Just grab the bottle and drink. The AutoClose valve works similar to the valve on the backpacks. It lets the water run as soon as you suck on it and is always ready for another sip.
Dishwasher safe and BPA-free polypropylene (PP) material
