I'm not sure if it's just my shirt. Both the website and the inside tag say it's made out of 100% cotton, but my shirt was definitely not that. It feels like nylon, what some rain coats are made out of. Because of this, the fit on me was pretty bad. I was pretty bummed because the design and embroidery is really damn cool. I would return mine, but unfortunately due to the shipping deduction with the return system it just simply would not be worth it.
