Have two river run I single tube floats that we use in pool and in the lake. They work great. Bought this to float down the gasconade river. Ran into some gravel bars and a few fallen trees. Was worried but it held up fine for the 7 mile float!!! It's not for white water or a constant level II or III rivers. Cooler did not leak but ice melted after a couple hours as expected. It was a fun time!
