This is a great deal. It was only $25 when I bought it.

This backpack is pretty spacious.  The only thing is that when I put a helmet in it, there is no more room to put anything else in.  Can fit plenty as long as you don't carry an extra helmet for someone.  Its nice to have a latch to connect straps so they don't slip off. Material isn't too thick but seems durable.  This seems to be a great commuter backpack.
