Introducing the humangear GoToob+, the new standard in silicone travel bottles. Modelled off the original, patented GoToob, the new GoToob+ keeps the features adventurers love – it's still made from soft, rugged silicone that's easy to squeeze, the small, medium and large sizes are still air travel approved (TSA), and all four sizes are food-safe (FDA). But the GoToob+ also offers a bunch of new features that no other soft travel bottle in the world has. It has a larger opening making it easier to fill and clean, and the bases have been contoured so that they can stand up easily. There are larger size indicators (making the size clearer to airport attendants so you can breeze through security) and they also come with the patent-pending LoopLock, which makes it almost impossible to accidentally open the cap, reducing the chances of leakage in your pack.
