The Nike Utility Speed Backpack offers a chest strap that adds an additional layer of security when hauling heavy loads to on the field and off the field. Durable, densely woven polyester fabric stands up to heavy activities, perfect for sports, travel, and everyday activities. It carries everything you need thanks to the spacious main compartment that fits your shoes and a change of clothes, side pockets for your water bottle, and interior slip pockets for small item organization. The zippered laptop pocket is big enough for a 16” laptop as well. The padded shoulder straps and back make sure you can carry your things comfortably, and when the weather heats up, the gusset vent helps keep your back properly ventilated. This Iowa State backpack is completely brand new, with no faults. Every zipper works perfectly fine. I also added pictures from the Nike Website at the very end for reference. Let me know if you have any questions. 😊👍
