I tried on an Alpine Stars jacket and it fit perfectly as a large. I ordered a Joe rocket that I liked alot better online and it is a bit too big, but I still love it. Just wanted to give a heads up that it appears to run a bit big. Here is my jacket, matches my all black 1000RR

 

true. my a* med is kinda tight but a small joe rocket on me is sorta loose, but perfect. im gonna get the cbr leather!
