Seats with kevlar cloth.. Durability?

Does anyone have seats with kevlar cloth that they can give an opinion on about the cloth`s durability?
It seems the cloth over seat bolsters tend to wear quickly so I`m contemplating replacing a few of the high wear areas with kevlar cloth. It seems to reason that kevlar would resist wear a lot better than factory cloth but I prefer to hear peoples personal experience.

Also, if anyone works with kevlar fabric for seats can you recommend a place to purchase it? I`ve been searching but finding the fabric is difficult.

thnx
