I was extremely disappointed with this luggage. It is made of durable fabric and the zippers are good. HOWEVER THE WHEELS SUPPORT BALANCE MECHANISM ON THE BOTTOM ARE MADE OF A FLIMSY PLASTIC AND THE BROKE OFF OF NOT 1 BUT 3 PIECES AFTER 1 TRIP! I HAD TO DRAG AROUND THE AIRPORT LUGGAGE WITH EITHER ONLY 1 WHEEL OR NONE! DO NOT BUY!OVERSTOCK WAS GREAT TO GIVE ME FULL REFUND.ROCKLAND POLO TAKE NOTE: MAKE BETTER WHEELS AND SUPPORTS. THAT IS KEY TO GREAT LUGGAGE!!!!!
