Nike Run Commuter Engineered Ultra Light Reflective Backpack Black/Volt. This is a wonderful backpack for running, walking, hiking, biking, or commuting with. It has adjustable shoulder straps, reflective strips to keep you seen in traffic, a chest buckle to lock down while moving, and a large main pocket with smaller storage spaces within. The bag has been used once or twice so it is not brand new, but it is the closest thing you'll find because of its years spent in my closet. If you have any questions, please do not hesitate to ask. Good luck and enjoy the backpack!
