This is an excellent little backpack!  I bought this for a little pack I could carry around the gym without having to leave my stuff in the locker and this works awesome!  It is extremely well made and seems far more durable (and larger) than the typical nylon sling sack that is easy to rip.  The cords are sturdy and the material seems very strong.  It has a nice zippered pocket in front and little pouches on the side.  The color is pretty and looks great.  It also hangs nicely on the side of the treadmill.
