I was skeptical at first, but I bought one at Bed Bath & Beyond because of the traveling I do every weekend. It is not leak proof, so I used a trash bag to line it. Over eight hours and using ice, the cooler got to freezing temperatures by the time I unloaded it. It is a great product that is light weight and stores easily!
Bottom Line: Yes, I would recommend this to a friend
It says right on the cover that it's not waterproof. If you order the Chill Chest Deluxe version that comes with a chill pack, just use a trash bag, it works great. I floated a river for two days, and 16 hours later my pop was still cold.
