I bought this undershirt for my hubby around two/three years ago. This undershirt is branded GT Man, and sized 32. This is a little bit bigger than his regular size, but since in the store where I bought it there was no smaller size, I had to buy this size. But it doesn't really matter since it's only a bit bigger. My hubby really needed undershirts at that time, so I knew I had to buy him some. I think I bought four or five at once at that time. This undershirt is 100% cotton (like it said on the label) and I think the fabric is the real 100% cotton, I could feel that immediately when I touched it for the first time. It's been a while now since I bought this for my hubby, but this undershirt still looks okay, though in some parts I could see some small torn. My hubby always wears this undershirt everyday when he's working. And he said that this undershirt is very comfortable to wear. Well, actually I wanted to buy him some new of these, but he refused.
