The GoToob+ keeps the features people love: it’s still made from soft, rugged silicone that’s easy to squeeze and gets every last drop out; 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. The GoToob+ features a new, larger opening making it both easier to fill and clean. The bases of all the GoToob+ tubes have been contoured so that they can now stand up easily for even easier filling. There are larger size indicators on the silicone (making the size clearer to TSA agents so you can breeze through security), not to mention the tubes come in new shapes, sizes, and colours. And we haven't even told you about our patent-pending LoopLockTM yet. The GoToob+ collar has our exclusive LoopLock, which makes it almost impossible to accidentally open the cap, further reducing the chance of any leakage. The LoopLock can also be used to hang the tube from a hook or clip it to the outside of a pack. There’s also a textured area on the collar where you can write in the contents with a permanent marker - the texturing helps the ink stay in place and prevents it from being rubbed off.
