This is literally the best water bottle on the entire planet. I can leave ice water in my car in 100+ degree weather all day and come back to freezing cold water with ice still in it. I have ice in it right now from yesterday. I had to buy one for each of my family members because they were mad that I was the only one with cold water at the end of the day.
Doesn't leak, doesn't sweat, and keeps your drinks cold forever. Seriously, there will still be ice in this bottle the next day.
