This snazzy dual use duffel backpack is made from recycled ripstop polyester with a TPU coating that makes it highly water resistant. In backpack mode it has adjustable padded shoulder straps and a sternum belt. Converts easily to a shoulder bag with a detachable, adjustable strap. Padded laptop pocket that fits a computer up to a 17". Luggage trolley sleeve allows you to slide it onto the handle of a roller bag for easy and secure toting. Used a few times, but does not cut it for the type of traveling I am doing. There are two tiny dark spots in the front bottom zipper pocket, shown in the second picture. *MOVING AND OPEN TO OFFERS*
