Back of seat bag for C'dale recumbent?

Can someone recommend a good semi-large bag that can hang from / attach to the support bars on the
back of a Cannondale Easy Rider seat? Something that will hold 3 Sunday newspapers, for instance, or
something like the design of the Vision seat-back bag.

Thanks.

I used a similarly shaped backpack from Wally world on a V-Rex for several years. I cut off the
straps I did not need and zip tied it to the back of the bike. You would not have known the
difference in appearance from an expensive seatbag....11 bucks.
