I have the Dainese Shotgun, textile + mesh(in some places.). Very light, awesome airflow, good elbow and shoulder armor. You do have to buy the add on back protector though. I got it from cycle gear for $180, although it lists for $290. Not sure why it rung up as $180. I also got 15% off for completing the MSF course!
