Wheeled backpacks are one of the most versatile forms of luggage available on the market. This multi-functional piece of luggage provides the option of hands-free carrying on the back with padded straps or the ease of pulling with the retractable handle and wide-tracking wheels. For those places where the terrain is rough, such as hiking up a mountain or through the woods, simply strap the bag across your back. On smooth surfaces, like the airport or on a paved path, the hand-pull and wheels can be used to give your back and legs a rest. Popular among students, they can use wheeled backpacks for transporting heavy books across campus. The multiple zippered and Velcro compartments, which can be found both inside and outside, provide ample storage for items of differing sizes, such as a cell phone, laptop, water bottle and clothing. Constructed from a heavy-duty, water and stain resistant fabric, wheeled backpacks come in a large assortment of colors and sizes.
