Looking for a cool, tough backpack for your kid? This 17-inch backpack (about 11x17x5.5 inches) is a great size for school, day trips, or sports. It's made from strong 300D/600D polyester that can handle being tossed around. It has one main compartment that closes with smooth double zippers, plus two side mesh pockets for water bottles. The shoulder straps are padded and adjustable, and the back has some airflow padding to keep them comfy. The design is a bold, vivid 3D 'combustion' pattern that kids and teens love. It's recommended for ages 6-16. Just a heads-up: try not to overload it past 4kg (about 8.8 lbs), and if it arrives with a slight new-material smell, just air it out for a couple of days. It's a solid, affordable backpack for daily adventures.
