This bottle it’s so amazing in pretty much every aspect, besides how beautiful the packaging is, I love the fact that this bottle is dent resistant, because I seemed to not be able to stop dropping my bottle, the material is almost like a rubber but it does feel like rubber, this bottle is just so good, the water stays cool all day and night until the next day, sometimes I can still see pieces of ice, it is very easy to clean and I love that it has a straw, even the straw has the same color from the outside of the bottle. It is definitely leak proof, if I could I would give it more stars .
