I have a question about fit on the Shift 967 Leather Racing jacket. http://shop.shiftracing.com/ecomm/ProductForward.do?forward=product.pagedef&proId=14004&cid=256&cname=Jackets&proNumber=70083&imgName=70083059F.jpg I usually wear a size Small in jackets and coats, sometimes an X-Small because it fits better in the shoulders. I don't trust the online size chart from Shift Racing. Anyone have practical experience on this one?
