Please check Revzilla or Dainese for sizing information.
This jacket is size 56. (Not a chest size)
This is a great leather jacket for riding. The big difference in my opinion between textile and leather is that leather does not buffet around when riding. It feels heavy but is great on the road. It is perforated so there is some airflow and this jacket can be comfortably worn through the summer.
It comes with the optional Dainese spine protector approx $90usd value.
This price is fair, I will consider a fair offer but not someone trying to buy it for a crazy low price. Dainese is high quality and valuable motorcycle gear.
