From Bric's, this Xtravel 19" Trolley Backpack features:   XTRAVEL 19 Trolley Backpack Wheeled backpack with iconic buckled outer straps. Made of recycled, water-resistant fabric. Two compartments: a padded computer pocket, and a very large pocket. With 2 wheels and puller system with ergonomic handle: the perfect solution when the backpack is too heavy to carry on your shoulder. Transform the backpack into a trolley - and vice-versa - in two easy steps: To use it as a trolley, release the shoulder straps from the snap hooks on the side and place them inside the zippered flap.  To use it as a backpack, turn the flap on the back around and attach it to the bottom hooks, to cover the wheels and prevent dirt from soiling up your back.  The grab system fits inside the special zippered compartment.  Lightweight with a back padding, making it extremely comfortable to wear.  With Bric s signature genuine leather handles.  Approx: 13 L x 8 W x 20 H (Weight: 4.8 lbs) Imported.
