Whatever you do… don’t ask for permission from your wife because she just won’t get it… But if you want the “worlds toughest” cooler… check out the Yeti Coolers. This things are made using rotational molding… which is just fancy words for very tough and built the same way they build kayaks. The hinges are unbreakable, ATV-tested rubber T latches, handles made of marine-grade nylon with ribbed rubber grips, screw-in, gasketed, leak-proof drain plugs, and padlock ports on both corners.
Fairly priced considering you will never have to buy another cooler again.
I love mine!
