Undoubtedly, hydrojug water bottles possess prominent hype and popularity worldwide, but still, some drawbacks why most people avoid buying these reusable bottles. Firstly, its size is pretty big for some users, but how can they ignore the lightweight feature when filled that makes the bottle easy to carry besides its massive size. The other drawback is that the Hydrojugs from the Classic and Pro collection doesn't offer insulation, making it difficult to keep water cold for long summer days. However, the issue can be fixed by investing in a neoprene hydrojug sleeve that makes it possible to provide you with cold drinks ideally.
