the shoulders are not too wide. However, they are cut without taking into account my rolled forward shoulders, because I'm guessing that most guys wanting it are not going to have my boxers shoulders. I took a fast pic to show this, but it won't load right now. I'll try again tomorrow.
It does remind me though, why fit pics áre such a bad idea for any product shot. Also, the Jacket will hit a standard 5'11" just under the belt line or dead on.
People can adjust from the stock measurements, of course, but it's typically not going to be an awesome idea to try to design from scratch.
Edit: more succinctly, the sleeveheads are not cut for my specific shoulders.
