It coverts with the straps is a backpack and when you want you put the straps into their sleeves and turns into carry on with wheels I used it for one quick trip because I wanted no checking luggage just a regular carry on and this one .. Worked wonders I didn't have to pay for a second carry on. However my shoulder injury doesn't let me keep it so I am letting it go even though is in optimal condition, nothing broken, no stains, no defects, minor scratches around the bottom. Almost new, one use only. Carry on Luggage Business Bag, Overnight College Computer Backpack Trolley Suitcase for Men Women Adults to Travel, Black
