The Classic Sports Cap Bottle from Klean Kanteen is a high quality bottle that's ideal for cycling, hiking and other outdoor activities.
The stainless steel doesn't rust and is resistant to almost all liquids. It also doesn't change the taste of the things that are kept inside it.
The 44mm opening of the bottle means that it's easy to fill and empty, and its rounded corners means that it's easy to clean. It can hold up to 532ml of liquid.
If there's an issue with the bottle, it also comes with a life-time warranty.
