Cycleaware Reflect+ Bike Frame Backpack

I bought this to put in the saddlebag of my motorcycle and use it to carry whatever I might buy when I am out and about. It does fold up very small. I cut the carry bag and helmet net off and store it in a quart ziplock. It is a little smaller than a full sized backpack. It will hold a very full plastic grocery bag worth of groceries.

I love the usefulness of this bag. However the durability is lacking. I use it to carry my books for school and the material is already tearing near the main zipper area. I am going to try and re-enforce it because as I said it is very useful and I dont have to wear a vest when riding because of the bag coloring and reflectiveness. It does fold down into a very small bag you can attach to your bike body, which turns into a small compartment for the back pack. I dont know if its water proof yet, however I will venture to guess that it is not.
