Color: Fluorescent Yellow Green Material: 100% Nylon Condition: Used very little, with no stains or scratches. I bought this for night jogging, but I never actually jogged at night, and I've outgrown it. As a result, I've used it less than 5 times. As shown in the photos, there's a pocket for a smartphone or music player, a hole for passing cables through, and a hook. Also, as shown in the photos, there are ventilation holes on the sides. I liked it, but I've decided to pass it on to someone who fits the size.
