i have the cl14 but i never eally wore any others, so beats me, although im alsways going too fast to even think some other type may have better airflow. on the jacket i have the icon neo daytona, try ebay sometimes u ca get a good condition leather jacket and in the summer,, (now) i odnt care i still wear it, it gets hot but its always hot in summer so i decided not to care about the heat and worry more about my speed. food luck riding and be safe
