The award-winning GoToob squeezable travel tube has had a makeover. Still made from soft yet rugged silicone, the GoToob+ has a larger opening making it both easier to fill and clean. The bases are contoured so that they can stand up easily for filling. A lockable collar makes it almost impossible to accidentally open the cap, reducing the chance of leakage, and provides a handy loop 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 to write in the contents with a permanent marker. The small 53ml size slips easily into pockets, bags, purses, and other tight spots. All GoToob+ are approved for airplane carry-on, they're food-safe (US FDA) and are 100% BPA-free, PC-free and Phthalate-free. Made in the USA and covered by a Humangear lifetime warranty.
