Full merino, size Large. In great shape no pills or holes. This is a classic and unlike wool shirts from today’s new merino brands this fabric will stand the test of time. I hate to sell, it’s just too big for me. Pit to pit - 22. Other sizes in pics. Rich dark grey with slight heather. This is 250 weight so truly three season, a little thicker than summer weight but I think this will last better.
