This bag is good, the vinyl is thick and should stand up to some abuse on the boat but the insulation is not as thick as I'd hoped.. This means the bag is good for short outings, maybe 1/2 day at most, but I don't think the ice will last a day in the bag. especially when you're opening and closing it to put fish in. If you don't catch any fish, then the ice should last all day. I'll try out this bag but if I ever have to get another one, it'll definitely have thicker foam. One more comment about the packaging....this bag was shipped wrapped in plastic sheeting and maybe even vacuum packed because the package was about 24" x 12" x 8" in size. When I opened the wrapping, the foam was smashed/compressed so much that it needed a day to regain it's normal shape. I guess they ship it like this to save on the shipping cost so to me, it was okay.
