I was looking for a 1.25" belt for my pants/shorts that have smaller loops, like my work uniform. Not sure why they couldn't make this gender neutral and offer standard sizes for everyone, but I suppose it doesn't matter. I have a 36" waist and ordered the XL, and it works well. A bit of a hassle to tighten it up since you have to hold it tight with one hand, and feed it through the other end of the buckle with your other; not as easy as it sounds. The buckle doesn't work quite as well as my 1.5" duty belt from another company, but I suppose it will do the trick for less than $20.
This belt wouldn't be so bad if it wasn't so stiff. The front buckle does not work well with this stiff belt because it sticks out an inch or two from your waist. I bought it and tried it on but have never actually worn it due to the fact that it sticks out so far from my waist.
