Easy mounting, under layer scratch proof, great quality.
Overall a very nice bag, I missed the simple and easy hook attachment system of my old Cortech tail bag. It is still a great bag at a good price.
Outstanding bag, I can fit all of my work clothes, cell phone and lunch and still have room. In the little rain that I did ride in, nothing was wet.
Only thing I would change is attach the rain cover to the bag but still able to be stored away. As it is right now it just fits around the bag, doesn't seem to secure and could fly off.
