Went on a river trip a few weekends back and got to bring this along. I was skeptical at first based off of never seeing or hearing about one of these before. At the end of the trip, I couldn't be happier about it. I brought four camelbaks filled with some beverages so I cannot comment on how many beers you can fit it but we had ice and the camelbaks in there the whole trip and they fit perfectly. I also had no issues with the thing getting a rip or tear in it and it went over its fair share of rocks. Very satisfied with the tube and look forward to using it again.
