Oogs,
While I'm not completely sure what you mean, I can say that I wear a Vaughn medium, and this unit fits like a glove. The arms are perfect length and don't interfere with my gloves in any way, and the shoulder floaters while wide, don't sit up too high on my shoulders. My ability to turn my head and look over my shoulder has never been better. Proportionately, the belly protection comes down to right where it should. I could handle it being a little longer, but it's fine.
I hope that answers your question. It was kinda vague.
