i've tried some although never purchased one... but, i can say: try it on, move around, put yourself in the position that you ride. i've put on a lot of riding jackets and some rock and some suck! it's just gotta be built for you. too much bulk irritates me and makes me feel like a freak when people watch me walk by but, not enough makes me feel like i'm gonna die if i crash... you decide
honestly, i like my old leather AGV with reinforced elbows, shoulders and forearms. it's an XL while i'm normally a L... but, I get cold easily and i like to be able to put 4tshirts and 2 sweatshirts on if i want to... the newer style jackets often dont allow for that as all their armor gets in the way and starts bunching everything up.
