On The Fly Kids 12oz Water Bottle Purple Hoot w/ Green Cap

Too big for the Grip-n-Gulp? Too small for the OTF? Try this on for size. Nalgene takes the 12 ounce bottle and pair it with the leak proof On the Fly Cap. They also made the silicone stopper a little softer so it would be easier for the little peeps to push closed.
