Many plastic drinking bottles smell of plastic and so does the drink inside. In addition, other drinking bottles cannot be cleaned well and they will leak. The ISYbe drinking bottle fulfills all requirements and wishes for sports drinking bottles. It is completely BPA-free, you can clean it easily and completely (also possible in the dishwasher) and it is really tight against carbonated beverages due to a new push-twist closure. In addition, a 10-year satisfaction guarantee ensures that the drinking bottle can be used for a long time and thus protects the environment. So its a perfect drinking bottle for everyday life.
