i like those too,Bought a couple of elasticated net bags to fit to the bulkhead behind the seats to hold odds & sods so I could get my map book in the tunnel storage pocket. Had to get some 2" wide Velcro with adhesive backing to mesh with the Velcro on the net bags. Results in the pics below. Not bad for a fiver
