SO when this boasted to stay cool all day I balked. Quite frankly, I need a water bottle that stays cold. I feel like I am adding ice to mine constantly. So when this claimed all day cold I just had to try it out.
First, this is very well made. It has a nice solid feel to it. It isn’t too heavy but you can feel the thickness. This was a good sign.
I tested it out first by just putting ice inside to see how long it lasted. It made it almost a full 24 hours. Then I tried out ice water. The ice seemed to melt a little bit faster with the water in it but it still lasted all day.
I am very happy with this and use it every day now!
