The humangear GoToobTM is the civilized, squeezable liquid transport tube for travelling, outdoors, and much more.Gone is the cheap, hard bottle that you can’t get your goop out of. GoToob started with soft, squeezable, food-grade silicone, and inverted the design so the contents are always at-the-ready. A special, highly-tuned valve in the flip-cap stops drips and keeps the cap spout nice and clean (no gunk buildup). A rotatable identification ring reminds you of the contents (“Was this my shampoo or my conditioner?”). Available in 3 different sizes: 1.25 oz, 2 oz, and 3 oz, all TSA approved for carry on.
