XS was too small, Small was too big. First I bought a small one which is a complete copy of my original which I bought at a military equipment store 10 years ago. However, the size is off. The belt was too big, I was on the last inside belt buckle. So I bought a size smaller hoping it would fit perfectly. It's not even tight, I was on the last buckle at the end of the belt. So now I have to try to live with my purchase. I could return it but I'm in the process of losing weight so I'm hoping it fits properly at some point.
