my husband loves this sweatshirt, especially the fleece lined hood. I think it does run big, he had a large which he 'swam' in. He is 6', thin, and the medium is fine even with a sweater under it.
I didn't have any doubts that this would be a comfortable sweatshirt. I was a little skeptical of the "Northeast Cotton" but after wearing this for a week, in a variety of New England Weather, i have to say it holds up very well. An Excellent purchase. I bought a second one, with the fleece lining, and that one is A++ as well. Don't hesitate, I'm sure this will be your favorite sweatshirt.
