I don't have any experience with Yeti coolers, mugs, etc. To me they're the product of brilliant marketing that convinced a lot of people to spend crazy money on super bulky and heavy coolers. To get the equivalent internal capacity of my 94-qt Igloo Marine (which has been great and has the snap on cushion top), I'd probably need a Yeti that weighs as much as a Volkswagen. I'm trying to keep weight out of my boat, not add it.
