When Beerman let TTOL know about the BOGO last year. We purchased 8 of them. I got my son & step son and son in law the backpack version. After they came in I thought I had screwed up. They just looked bulky and hard to carry. They LOVE them. We use our 48 every weekend on our boat. Can't wait for their BOGO this year. I tell everyone about Polar Bear ice chest.
