Efficient use of under the seat space

Efficient use of under the seat space
Just loaded this up and installed it today. Size is pretty much as advertised. I was able to get 3 allen wrenches, CO2 inflater with 3 CO2 cannisters, spare 700c tire tube with small plastic tire spoons, small wrench with multi-bit set and tire patch kit inside and it's pretty much stuffed. I read where some reviewers said they used this bag to hold their lunch. It would have to be a pretty small lunch to do that.The bag appears to be made of quality material and the reflective piping around the perimeter is really nice. The zipper looks to be well made and closes very tightly ( highly water resistant). The bag attached securely to the seat frame and seat post and is secure with no wobbles. There was still room on the seat post for my tail light after bag install.All in all this seat bag is just what I needed and looks great. I'll update this review if the durability turns out to be unacceptable.
