This piece of luggage has quickly become one of the most popular in the line. It is perfect for 2 to 4 day excursions. The retractable handle and protective wheelbase allow one to roll it over curbs and stairs with confidence. Passable as a carry-on on some airlines it may be an inch over limits on others, however after traveling extensively we have yet to find an overhead compartment that will not accommodate it. (Slide the handle of the Shoulder Bag or Piggy Back over the retractable handle and roll two bags at once.)
