This rolling backpack for kids and adults converts from a rolling back on wheels into a wearable backpack with shoulder straps. It features a large zippered main compartment (34.5 liters) with tablet sleeve, 2 zippered front pockets and 2 mesh side pockets. The double-tube telescoping handle makes it easy to pull and maneuver, while the backstraps tuck away in the convenient rear back pocket—no having to unzip. Double wide backpack wheels roll and turn effortlessly on sidewalks, paths and airplane aisles. When not rolling, use the cushioned shoulder straps to wear like a traditional school backpack, or carry with the padded top handle. The bottom stand keeps this rolly backpack upright when parked. Made of durable ripstop polyester fabric with a metal frame, this rolling backpack for boys and girls has a water-resistant coating to keep your gear dry. Measuring 19.5 x 13 x 9 inches, this backpack works great as carryon luggage for airplane travel. Our Promise - at J World New York, we stand behind our products 100%.
