Excellent belt for work and sports; It stretches with your body as you bend, squat, etc. It stretches constantly over time, so make sure you buy the right size. I got a medium (32-34 I think) a few years ago and over time it got so long that the end of the slack reached the back loop of my pants! So this time I ordered a small (30-32, my pant size is 32) and it fits perfectly and I doubt it will be one ponytail like the other lol.
