Nice size. No odor or taste to the water after sitting in the canteen (unlike others I've tried). The protective spout cover doesn't come off easily--that's my reason for only 4 stars.
Bought this canteen for my son to use at school. My daughter has one in a different color and she loves it. It washes easily and seals tightly. It is easy for them to open and drink from, and closes easily and securely to bring home.
I bought two of these for each of my granddaughters(5 and 7 years old) They loved them! I had their names(first and last) engraved on each and they especially liked that and they showed up very well on the bottles. There were no problems with leakage and we liked the fact that they will keep hot liquids hot and cold ones cold. We had no problems with noise from the bottles when drinking as was mentioned in other reviews. I would recommend for other children needing water bottles for school.
I ordered 2 of these canteens for 2 of my co-workers which I also engraved their names on them. When I gave it to them for Christmas they loved them! When I saw them I want one too! I remember when I was younger I would drink from an aluminum sauce pan and drinking cold water from them made the water taste so good. These canteens give the water that same taste! I would recommend these to those who like the taste of refreshing water.
