Most hotels and gyms offer complimentary toiletries, but those who like to bring along their own favorites have probably noticed the hospitality often stops at precious shelf space. Enter the GoToob. Designed by San Francisco firm Humangear, the squeezable tubes have built-in suction cups on the back that cling to most glossy surfaces. They're a useful update to Pkoh NYC's Silicone Travel Bottle that we wrote about a few years ago.
In addition to the suction cup, GoToob's "no-drip" dispenser keeps its contents cleanly inside, and a wide-mouth cap easily twists on and off for refills. The tube also has an ID window that rotates between the labels "soap, shampoo, conditioner, lotion and sun" as a handy reminder of what you put inside.
Selling in several colors and sizes, the PBA-free GoToob sells online and at stores like REI, The Container Store and Flight 001. In the U.K. try Amazon. Prices start around $6 for a 1.5-ounce tube, but suction cups are only available in two-ounce sizes.
