Bubi Hatch
The Bubi hatch is a unique way to keep your bubi contents the same temperature or just a convenient way to walk or run around.  It is specially designed for the bubi bottle since  the bottle is so flexible that normal holders fall off.  We remedied this by adding a strap to go around the biner to make it secure.Use it and scrunch up the bottle,  maintains the same wonderful feel and will not clang around.  You will love it.
