This is the best bottle on the market!!!
It's guaranteed not to sweat, hold cold 24hrs, hot hot 12hrs.
I had ice stay in the 24oz for 72hrs while traveling Florida. It was 91F outside.
I also poured pipping hot coffee in the bottle, then placed it in the freezer. 6hrs later the coffee was still so hot I could not put my finger in it.
When you buy a bottle the company will donate 5% to what ever organization you would like, well as long as it's not your retirement fund.
Lifetime warranty is awesome!!!!
