A pee bottle is nothing more and nothing less than a plastic water bottle with a wide mouth. This way, it’s easy to pee in.
It comes in the shape of the bottle displayed on the image. It looks exactly like a water bottle you could use for drinking. Therefore, it’s recommended to label which one you would use for pee.
However, it’s also available as a water bag with a wide mouth. In this form, it takes up much less space in your backpack.
