Grabbed this travel backpack recently because I have always preferred one to a shoulder bag. This one is like a carry on but still fits under the seat! It has a bottom pocket for shoes, a water proof pocket, and a large main compartment where you can pack clothes, too! Just an FYI if you pack shoes there won’t be as much space for clothes since the compartment inserts inside the main compartment. It has a side pocket for water and buckles to keep things contained. I couldn’t pass up the green 😍 only thing that would make this better is two side pockets vs. one LTKTravel
