There is a universal size and one size fits all option. What is the difference?

Just a glitch. It depends on the color you choose as to which will come up. 6 or half a dozen. Same thing.

As far as I can tell, the drop-down is telling you that there is only one universal size. If it is tight, soak it first, then put it on your head and it will stretch out slightly. My head is large, but I have no problem with the size (although it is very snug).

Its one size fits all. There is an adjustable strap in the back. Fits most.

They are a standard size, yes they will fit the one size fits all models too.

Sorry. I really can't answer that one. I just got the XL and they fit me fine and are very comfortable. I do believe they are 4 different sizes and other that size I would assume they are the same.

the listing covers both sizes -- there are check boxes below the description that allow you to choose which size you want

You must have gotten to that page via a search. Click on the by SCC link (under the product description). That will take you to a page showing all their products with a "See Size Options" for each one

No these are "one-size fits most" but they seem to work with a lot of different sized people. I have used them, my brother has too, and my 11 year-old daughter has and they work well for all of us.

There is no difference in size, there are different colors so you can select according to your own personal taste

I am sorry, but I don't know the answer to that question since I only bought one size and have no basis for comparison.

A little ambiguous, but I believe it means that there is only one size for this model. Which is true.

They come in different sizes. I'm sure that you will find a size that fits.

It is one size but it does adjust quite large. It would not be tight on someone who is really small though.

No, one size fits all because has a belt that you can adjust according with your waist. If you can read said: 22" -46" inches that's is the size of this belt that goes around your waist. I bought this product for my Mom and cut it to adjusted to her. I hope I help you. it really help with your posture.
