We bought this for a trip to the Caribbean to hold our daughter's car seat. It held up fine on the way there but on the way back it burst at the zipper. When we went to baggage claim, the empty bag came out first with baggage tag then our car seat came out several minutes later. I'm surprised we got both back. I returned this to Amazon for a refund. It is a shame since it seemed like a very well constructed bag with heavy duty zippers and material. It may just be that we got a defective bag. I may try another one in the future (maybe they'll improve the zipper issue or I'll get a non-defective one).
