Thank you for viewing! I've used this a few times when traveling. It's a very lightweight, foldable backpack, so it's convenient for travel! It can also hold a water bottle on the side! As shown in the third photo, you can also slide it over the handle of a carry-on bag! There's a slight fraying on the shoulder strap of the backpack (photo 6), but I think it can still be used without any problems. There is also some minor print wear, so if you are okay with that, please consider purchasing. Actual size: Approximately W30cm x H40cm x D12.5cm
