Cool Cooler.
My wife likes to make the most of the sunshine and sits with our neighbours a few doors down. Used this for her to take a few beers round and both thought it was amazing. I'd put 3 x 1Ltr bags of ice in and a dozen cans. This was around 1pm, went to empty it out just after 12.10pm the next day, and guess what? Yes, the cans were still ICE COLD! 10/10 from me.
