It's micro diamond texture reduces visible abrasions. It also has a fully lined interior with elastic garment straps, and interior zipper pocket for delicate items, top and side handles that make it easy to lift. The All-Purpose Travel Backpack is built with water resistant ballistic nylon. There are two main compartments, one padded compartment to hold a 19" laptop. Both are compliant with carry-on measurements and attach to each other for comfort.
