I received this model in time for a four day kayak camping trip on Lake Umbagog in NH and Maine. I filled the icemule on Thursday AM with 12 beers, 8 frozen water bottles, food that needed to be coldish, and a small piece of block ice. Strapped the cooler on the outside of the kayak and headed for our campsite. Once there, it just sat in the shade at our site until Sunday AM where what was left was still cool (the beer Saturday night was still cold!!!). Very impressive performance!!! Nothing spoiled!! Definitely opened some eyes with the folks we went with. The cooler is big and can be heavy, not sure I&#x27;d hike too far with it, but a trip to the beach or back in the kayak somewhere, it to do great based on its inaugural outing. Will be fun to keep testing it. Sure beat the hard sided cooler and other soft sides I have tried in the past for a trip like this, by a landslide!
