Since slimming down my waistline, my weight belt tended to slide up when inverted...not anymore. And I like that it's still quick release with the pin style belt buckle. Be warned that this won't work with the plastic style non-freediving belt buckles.

It's funny how something so simple and inexpensive can make such a difference for you. My weight belt was constantly sliding up around my stomach while diving and would also turn and be in the wrong position when it did. Nothing worse than going for air after a long dive and having a weight belt right around your belly restricting you, totally uncomfortable and a pain to keep repositioning. This allows me to have my belt a little bit looser to so its always comfortable and I never have to touch it once the whole time I'm in the water. Funny enough, it's one of my favorite pieces of gear.

I’m thinking this will keep my weight belt right where I want it

If you've ever found yourself having to adjust your weight belt after (during) every dive, then this is what you need. With a rubber belt, my weights stay put on my hips for the entire dive. Breathing and relaxation are improved, stress is eliminated. Can't live without this.

I'm not a big guy and I find it to be too small. I didn't see sizes to order? I wouldn't think this would fit a larger guy.

Very well made. It works as advertised. Keeps the weight belt from riding up during a free dive descent head down.
