I plan to go on a hike or go camping. Is it possible to use the cup outdoors?

Using the cup isn’t an obstacle to enjoy your favorite activities. As with the public restrooms situation, it is a good idea to have wet wipes at hand to clean the cup with. All sorts of disinfectant gels you apply on your hands to make sure that the cup doesn’t interact with bacteria. Despite the chemical compounds these products contain, they are still useful when handling the cup outdoors.
