45L Travel Backpack

See screenshots at end for all product details/specifications. I used this backpack for 10 days in Europe in May visiting 3 different countries and doing laundry once. If you have compression packing cubes, it will definitely fit what you need on your journey! It does not fit comfortably under the seat (though I did have to keep it under the seat on one flight), but it fits easily in overhead cabin. Does not qualify as a personal item but I did get away with it on 3 out of 4 flights! So much easier than rolling a suitcase around but it does get uncomfortable to walk longer than 30 minutes because of how heavy mine was.
