Tal 20 oz Stainless Steel Insulated Modern Water Bottle, Purple Glitter

On the first day that I used the cup, I filed it with ice and water and took it to work. After drinking the water, I added more water to the ice and drank about half of it. When I went home, I realized that I had forgotten the cup in my car. When I got a chance to go out and opened the container to empty and refill it and there was still ice in it and it was still extremely cool. I also put coffee in it before, and it kept my coffee warm for over half of the day without rewarming. I would highly recommend, plus the colors are just to vibrant and pretty.

really cool water bottle. I put in freezing water and it kept the same temperature for 5 hours. I checked back at 17 hrs and it was not as cold but it was still chilly water. I checked back at the 22 hr mark and it was colder than room temperature but not by much, I kept it at my desk indoor. Its a good size, a whole water standard water bottle and 4 more oz. Only way i can drink water its if its really cold and this bottle does the trick for what I need.
