I bought this jacket in the spring of this year. When I got it, it felt a bit snug, I was told it would break in. After six months and a few thousand miles, it has broken in, but isn't comfortable with a fleece or any other jacket under it. I called Aerostich and I can have it altered, but by the time I pay for the alteration, I figure I would come out better selling this jacket and buying a larger one. This is an Aerostich Hi Viz Roadcrafter jacket with no custom fitting, it is a 42R. For reference, I am 6' tall, 180lbs, 34" waist. The jacket fits me fine until it gets cold and I want to wear extra insulation under it, then the shoulders are too tight. I would like to get $375 for it. Aerostich has a fit chart on their website:http://www.aerostich.com/
