Promising review: “Well this is the coolest thing ever! I travel quite a bit, and I usually don’t take a bottle with me because they are big and bulky and I usually lose them! This collapsible water bottle is a perfect traveling accessory. It stays collapsed until after security, and then I fill it up for the trip. It’s a good size and fits in my side compartment in my travel backpack, and the cap screws in securely so I don’t have to worry about it opening accidentally and spilling all over the place. I follow the instructions on how to clean it and it works just fine.” —M. Lyons
