I had a cycling specific gear bag that I got cheap from Performance a few years ago that had one ventilated end compartment for shoes, two other moderately small compartments, and a big compartment in the middle for helmets and clothes. It was just a little too long, but I really liked it. Unfortunately it was stolen a few days ago. I can't really find many cycling specifc bags out there with mesh pockets for shoes. Anyone have a particularly good one?
