For some travelers, drinking out of an actual cup is preferred over a water bottle, so instead of bringing a large mug that takes up space, the Popware Collapsible Travel Cup will be a much better option.
The Popware Collapsible Travel Cup is a pretty good option for any traveler who feels the need to have mug with them at all times. It's small, lightweight and it can be clipped on to the water bottle thanks to the carabiner clip it comes with. Best of all, it's collapsible, which means it can be flattened so that it doesn't take up room in the backpack. The cup is also constructed from TPE, an eco-friendly material that makes it 100% recyclable. It's a good accessory to have on any backpack adventure.
