This is seven discs down below. You have about 6cm of space left in the main compartment in this configuration.
This is 5 up top, 2 down below for your total of 7. There are a rain coat, a light fleece sweater, and rain pants in the main compartment with the 2 discs. There is a pair of gloves in one of the side pockets. And the other side pocket is practically empty.
I did find out that the plastic stiffeners for the sides are removable so that might give a bit more flex.
