I have had this bag for about a year now and it has served me well. I use it every day to carry my essentials and it is perfect for bike rides. There is practically no wear or damage to the bag, but I take pretty good care of it. To give perspective on the size, it is holding my encased Nook, work
gloves, notebook, 15mm wrench, multi-tool, Wayfarers, and medication in the main pouch -- with plenty of room for more crap. It is a rad man-bag.
