Question: Is this cooler waterproof?  My last cooler ws great, but it leaked a LOT which meant an incredibly sandy mess.
Document: Bought this for a honeymoon couple that were taking the train to Savannah and Ft. Lauderdale.It was the perfect gift for the long ride and I stocked it with lots of great things for them to enjoy on the ride
This backpack cooler bag is just what I'd been looking for and at the right price. Haven't used it yet, but it appears really good quality. It does seem a little bit smaller than it appeared on the order webpage, but no real problem there.

Answer: no
