Features: 19 compartments in total. Expandable with a zipper in order to accommodate larger capacity. Strap to secure on a rolling luggage. Adjustable and padded shoulder straps and back. Built-in laptop padded compartment, power-bank charging cord and a headphone plug-in spot. Perfect size for a “personal item” as many domestic airlines. Condition: Excellent, no visible flaws, perhaps just minor signs of wear. Nothing is wrong at all. I just have so many backpacks so I have to let go of some. Please inspect all photos for condition and measurements. Ask questions. Offers are welcomed :) #backpack #travelbag #carryon #luggage #laptopcase
