This is a brand new item that I purchased for my Husband as a Christmas present he did not like. So, I am listing it. The size was supposed to be a 3X but measuring the pit to pit measurement of 29 inches it might be a larger size. The shirt has no size. I think it’s either the 3X or the 4X. I have taken several pictures if you would like a specific one or if you have any questions, please let me know. This item comes from a smoke-free home. Thanks for looking.
