When I first heard about this bottle, I was quite skeptical. Can a bottle really keep something cold for 24 hours? Needless to say I purchased it from EMS and test it out. I put ice and left it on my desk at 10 pm. I checked 24 hours later and there was still ice in it. Amazing!!! I went out and purchased the 64 oz growler one week later for family camping.

The only thing I would improve is the cap tend to leak even when fully tighten. Also the loop from the cap seems too fragile and using it to carry the growler thst holds 4lbs of water is asking for trouble.
