as in another thread, i mentioned i would not do track thing. but i am cautious, so i am thinking of a back protector it seems every owner of a* leather jacket uses a* protector. however, i do remember the BEST back protector is not from a* nor dainese, but another brand. a UK brand, i think. it is above 100 pounds, and is not sold everywhere. i found a uk website sold it. but i forgot the brand name. do anyone remember?
