This is my second Mule cooler- which is saying something, bc I purchased my first one more than 6 years ago. It is fantastic! The only reason I needed another was because I gifted my son the last one. It's very watertight with the roll top closing, and holds items better than the traditional square/hard side coolers. Yeti has nothing on these, and I have both (not that Yeti is bad, but my Ice Mule is just as awesome and effective). I like that I can carry it crossbody like a backpack and love that it packs down so small when empty and I need to put it away. Ice can stay for days. I totally recommend these!
