I got the carpet in. It's their "OEM plus premium" carpet. I got the basic with the standard backing. It's seems just like the OEM backing. Same material/thickness. This carpet is 100% nylon. I'm not sure what the factory carpet was made of, but it seems a bit different when examined very closely. I'm sure it would be stain resistant, but that probably isn't too big of an issue with black. It seems a bit more flexible than the original. Haven't installed it yet. Can't comment on the Jax carpet, but I'm happy with the carpet for about $129.
