Input: I bought four and two of the four were leaking water from a rip in the bottom. There were the first time they were used and were placed in the back of a truck. They did help protect the kegs from the warm elements but I don't know how much insulation the bag provided based off the speed the ice melted in. I wouldn't buy again for the money as I'll continue to use them simply because I have them until they wear out.

Great concept but not ideal for transporting kegs.
