I was pleasantly surprised. It's a nice heavy weight flannel, and fits the way I'd expect a men's medium to fit me. I'm a small female (5'3), medium build (not heavy, but not skinny either) but I have shoulders too broad to wear a men's small. This material does shrink considerably, being all cotton. My husband wears a large, he tried it on, and while it fit, it was way too snug (as expected), and if I was going to order him one, I'd go with an XL, but we like our clothes roomy. A large would fit him, but that would probably be pushing it. Hope this helps anybody trying to figure out their size. I'd go one size up.
