What he said. I'm about 5'10" 180. Normally I'm a large, but with broad shoulders and a barrel chest the fit is too snug at the top for me. I love the layer and will be buying the next size up after I turn this over. I have experimented with it with a 145 and 210 under, and the 240 hoodie over. Its just a little too restrictive once the 240 goes on. I really want it over the 240.
The perfect buyer is someone who wears a KUIU M top, or a "normal" shaped person who wears a L and wants their puffy earlier in the layering system.
Thanks Derek.
