This truly is the coldest water bottle! Whenever I go to work, I leave my food and water sitting in my car, even in the dead of summer. Then on my breaks I go out to my car to eat and drink. Usually I have a glass “insulated” bottle that I use to bring my water in, so I just always know that whenever I go out to eat my food, I will be having warm, and sometimes boiling hot water with it. So when I used this bottle, I was so pleasantly and thoroughly surprised when I took down a gulp of ice cold water. The outside temperature had not effected the water one single bit. I’m talking about bright, sunny, 70 – 80 degree weather here. I don’t know how it works or what makes it work, but this bottle is an absolute blessing!!
