This is probably one of the worst-made garments I've ever seen. I know there's a lot of discussion about the multiple manufacturing sites, mine was made in Haiti, if that helps anyone out.

I bought a small when I'm usually a medium (after a few washes) in these type of cheaper shirts (Hanes, FTL, etc.) because everyone said they run large. This is only partly true.  The shirt was VERY long. I'm 5' 10" and the small came to my mid thigh. The sleeves were big and billowy around the bicep and super tight around the forearm and cuff. I'm not a huge guy, but a small should NEVER be too big on me. It honestly felt like three different shirts combined, somehow. The material was also pretty rough. I don't think fabric softener would have done anything to make this shirt more comfortable.

I like Carhartt as a brand and know that they have some goods at higher price points that will last a lifetime. This shirt, or at least some of them, aren't getting the kind of attention their jackets and pants receive. Stay away or go find it at your local Army Surplus store to make sure you're not wasting your time.
