Mossy Oak Series Family Pack

Used this on a 2-week sailing trip in the British Virgin Islands with 6 of the recommended COOLER SHOCK 18degree ice replacements. Had a 4-fold purpose: 1) take high quality meat and salmon we could cook ourselves for a party of 6 to save literally $1000+, 2) keep sunscreen, shampoo, and other liquids frozen so we could "carry-on" them through multiple TSA security checks, 3) keep ice cold on the sailboat , 4) easily carry ice and cold drinks to beaches.The 24-count size was a little large for under-the-seat carry-on so we had to check it. Would have fit in the overhead compartment. Kept everything frozen super-hard through 3 connections, 12+ hours, long layovers in 90+ degree heat.As others have recommended, turn your freezer down as low as possible to get everything frozen to as low a temperature as possible (ours goes down to 26degrees). Put the AO Cooler in the freezer overnight before leaving so it is also as cold as possible. I loaded the AO Cooler before putting it into the freezer because I was not sure if freezing it first would cause it to be brittle or difficult to load. Note that because of the "soft-sided" nature it was easy to squeeze it into our freezer after loading. This also made it comfortable to the touch when carrying.Realistically, when using this for ice for drinks, keeping beverages cold, etc. it really only works for 36 hours. Each time you open it decreases the time the ice stays frozen and by then end of 36 hours it was generally all melted water (still cold, but melted). In comparison, the regular Igloo coolers supplied by the chartering company only lasted 12 hours. Note that most ice we got seemed to be barely frozen at 32degrees and melted super-quickly.I would recommend getting 4 of the 10”x9” MID-SIZE-COOLER-SHOCKs for the sides of the 24-Count AO COOLER and the 5-pack of the COOLER-SHOCK-LUNCH-SIZE-PACKS for the ends and top. The 10”x9” were too wide to fit at the top. As per instructions (and science) it makes little sense to put the COOLER-SHOCKs at bottom.I cannot say enough about how sturdy this bag is. Only wish is that I got the backpack version as this is quite heavy when fully loaded.
