Looking for a water bottle that can do just about everything? Take a look at the Golchi, the swiss army knife of liquid containers. It really is much more than merely a water bottle. It can hold both hot and cold liquids like your usual metal thermos—but it can hold them both at the same time. In addition, it can be configured into many different convenient sizes, depending on what you need that day. The separate modules all easily untwist from each other, so if you want to just carry around a single drink, you can easily do this. It also features a dry storage compartment so that you can carry everything you need in one container. This startup product aims to be the last bottle you will ever need.
