The Rollux Versatile 2-in-1 Suitcase may look like a carry-on bag, but it actually expands to a full-size suitcase. In its carry-on form, this travel bag holds 41 liters of gear. However, when you fully pop out this expandable suitcase, it holds a whopping 93 liters of your stuff. That means you have more than enough room for all your souvenirs in the Rollux. And you won’t even have to deal with frustrating baggage fees. Additionally, this bag includes a built-in USB port to make charging your electronics super easy on the go. Thanks to flexible sides but tough corners, this suitcase ensures packing is easy and your belongings stay safe. With 360-degree spinner wheels, this bag navigates with ease. Finally, when you want to carry it by hand, simply remove the wheels.
