What do u mean by that? It's just a regular sized backpack I guess not small or too big

There is no difference because they all say "One Size" meaning that they are all the same size

I bought at the time the only Jansport Mesh Back Pack offered by Amazon thinking that I was buying the same size and model that I currently have, to my surprise, it was much bigger in volume, same model and design but bigger, didnt know it came in several sizes.

I didn't know there were different sizes. The overall size of the backpack is pretty big. My son can fit alot of stuff in it. Other than the main compartment, there is a small pocket on the inside that velcros shut, and then a small compartment on the outside of the front that zippers shut.

I didn't know there was a choice of sizes. The one I purchased was normal backpack size.

No difference. Think is different packaging. Just take note the volume. As I think it comes with 2 sizes.

Unsure, but the #3 is 6 inches and I think #4 is 6.5 or 7. #3 is pretty good size and fits my needs.

Well... does it come with 3 sizes or not? "Extra" seems an ambiguous term here...

There are three sizes. You can select your size preference when you place your order. I ordered size 34x36.

All three are the same mesh, similar to window screen. They are of very nice quality, but would be MUCH more useful if there were three different sizes.

As far as I know they are all the same size. I was not given a size option when I purchased it.

There are 2 sizes as far as I know, and I guess you may get the larger or the smaller one. Make sure what's available!

There seem to be three options to purchase - a 55cm, 65cm, and 75cm. They're different colors depending on the size selected.

They are all standard. I don't have measurement but roughly 10 inches. It's the grip width that has differences. I believe one is Olympic and the other is called standard. Google it. Not a lot of difference

It was a gift for my sister in law and I do not remember the sizes. The middle one is bigger than the other two.

It comes with three different sizes... It matters on who you're using on- adults, young children, infants, etc
