It's a medium but it shrunk to a small after washing it. Worn and washed one time only. Some measurements:
Neck to the waist (front) - 21"
Upper shoulder to sleeve - 20"

I'll be glad to take any other measurements. As you may know, Momentum went under and these are no longer for sale. Sold

 

ill take it

 

Where did you buy this?! I have been looking for a place to pick these up for a while. I emailed them and they just said to go through one of their vendors but noone has anything.

 

Through their Facebook page. But it was last year when they were still in business.
