A squeezable silicone travel bottle with a flip-top cap over a silicone valve, and a locking collar humangear calls LoopLock. The company claims it is the only travel bottle with a locking cap, which is the feature that matters when a bottle of shampoo is riding loose in a drawer in the back of a truck.

TSA: humangear states this size is approved for carry-on travel.

The tube and the cap valve are silicone; the collar and cap are #5 polypropylene. The collar carries a textured write-on patch so you can label what is inside, and it will hang from a clip. The tube is contoured to stand up on its own while you fill it. humangear sells replacement flip caps separately.

humangear does not publish a dishwasher rating for the GoToob+, so we do not claim one. Nor does it publish milliliter capacities — the fluid-ounce figures above are the manufacturer’s own; any metric equivalent is a conversion.

humangear styles its own brand name in lowercase. Liberty Mountain's catalogue lists this item as “GOTOOB+ SMALL GREEN”; the name above is humangear's.
