Spacious is the first thing you will notice. 28+L is the capacity. Ample pockets (9 in all) to keep papers, business cards, pen, documents etc. 2 Set of Elastic Cables for laptops, to keep the laptop in one place. 3M Reflectors for night riding. Tough nylon fabric, same which is been used for our Highway 500, Highway 700 etc. One can use it as a cross shoulder bag apart from using it as a backpack. You can lock the zipper for better safety.
