I know the airflow difference between perf to non perf in jackets. I am just curious if there is any structural difference. would a perf hold up less than a non perf. enough to make a difference? I am thinking that i would rather have a perf because the one i am looking at has a full zip out linet, really comfortable, that cool speed hump( yea i dunno i like the look of em), and good armor all around and its only 225. i doubt that is a big difference but im just curious.
