Seat Net?

[Rado]

Not sure what to call it but is there a Net/pocket kit you can add to the back of the front seat for light storage?
On the back of the front seat of my HHR I have a net pocket
.(like a small cargo net ) Great to throw in the dog leash and safety vest! (She is small so I want a bright vest lol.)
I have seen some wit small pockets but prefer one large pocket.

Thanks Rich
