The MiniGrip with Loop-Top cap has the same size opening as our standard 32 ounce bottle and takes the same 63mm Loop-Top closure. This bottle is super easy to fill if you want to schlep your smoothie to school, or anywhere. And since it is so easy to fill it is also just as easy to clean.
The MiniGrip with ATB comes with our bike bottle cap. If you want a leak-proof bottle that is easy to drink from on the move, this might be it.
