I'm a 38 waist which belt should I go for and a big belly to.

A Large if you use it for short durations when weightlifting. An X-Large if you plan to use for work.

I have a 24 inch waist. I bought the medium. I think you should get the large or even the extra large, if they have it. Definitely the extra large, because there's enough to tighten as much as you need. Good luck!

I have a 38" waist depending upon how many donuts and have about 2" left on the belt

I can't say for sure but I can tell you how mine fits. I have a 38 inch waist and the large belt is plenty big. I could easily be 4" wider in girth and still use the large. Does that help? My uneducated guess is that the XL would work for you.

I would go with the medium. I have a 34 waist and the large was just right. the length should not be an issue due to the elastic binding at the ankles.

I would think the large would work, but I am not sure. You might try it. If you have an aqua exercise location, they might use those belts and you could try them. The location I go to has two or three different sizes.

Get a large. As you lose weight, you can tighten the strings. You want to be comfortable.

You will want a Large, which is for size 36/38 according to the size charge that came with the belt.

I am 6 foot 2 tall and 190 lbs with about 3-4 inches more in waist than 10 years ago at the same weight. I use to wear a 32 waist in Levi's Jeans, now a 36 waist is baggy but the 34's are too tight. I have a very slight belly. I wear this around my naval area and it stretches, I would think it would fit a true 36 inch to 37, possibly a 38 inch waist. I know the tighter the fit the more it will pull in your gut and your lower back. The length of the brace is 39 inches long laid out flat UN-stretched and stretched I easily got it to 46 -47 inches. I hope that helps you make a better educated decision to buy or not to buy this Mr. Firtel. I am 6 foot 2 tall and 190 lbs with about 3-4 inches more in waist than 10 years ago at the same weight.

I would go with large. I weigh 157 lbs and the waist is between 34-36", the large one was comfortable, on an under garment you do not want a tight feel, the outer pants you can tighten to your liking with the belt. these are quite warm, when worn will a good pair of pants will protect you from cold environment for extended exposure to weather.

I got the large and my son is a 34-36 waist. Another thing you might want to know is they are gathered and a little full looking, but if the XL is too big you can exchange, but I would do the XL for 38 to be comfortable. JMHO.

I would go with the waist measurement. But to be sure call the company and ask them then you can also ask about returning it if it does not fit.

I got the belt for my son who wears a 42 and he wears the xxl. I hope that will help you decide,

I'm a solid 34 and I got large size. Fits perfect. 33 could probably go either way (L or M) but if you got inches to lose, I'd probably get M cos you might find the L to big after a bit of weight loss...

If you are closer to size 42 then I would go with large if you right at 40 then you could go either way.

My waist is larger, I bought large when I should gotten XL. Sounds like you could use Medium.

I have a 36 inch waist and got the large and they were just the right size so they would probably be super tight on a 38, I'd get the xl just to have the extra breathing room.
