I’ve got the large bag and the 45. The bag is a pain in the ass to get into / out of. The 45 gets two bags of ice dumped into it and drinks / snacks thrown in, and where it then sits in the shade on my boat for 6-8 hours. I’d estimate that roughly 90% of the ice melts into water during that time, until I come back in. The bag seems to be a little worse. Am I missing something? What do y’all use instead and is anything better?
