Just thought for those of you that have older jackets this might be a possibility. I went to Bimmerfest last year at Mosport and picked up an Airflow jacket and Santiago pants from the distributor that were 'last generation' models. I then went to the local BMW shop and ordered a set of the upgraded 'NP' protection pads for both. It cost me about $180 and a tailoring charge for the jacket to accept the larger back pad that was the replacement for the original. Not a bad deal if you are feeling like taking advantage of newer technology and haven't got the funds for new clothes. I find it very comfortable since it form fits when your body warms it and I've been told that its the best out there.
Just a thought, as I said...
