I know this is an old post, but figure id add...
I recently have been looking into quality seat covers (necessary as an uber driver). I came across www.coverking.com
where they custom make seat covers for vehicles. They are on the pricey side but they do offer a custom made set of Ballistic Nylon seat covers with MOLLE straps for the back of the seats. They come in multiple colors to go with the look of your vehicle and are supposed to be extreme duty and great quality.
I just purchased (still waiting for them) a set of cover king rhino hide seat covers for my crosstrek. I'll post pics and start a new thread when I get them installed.
Forgot to mention: These seat covers being custom made take into account the seat airbags and have break away spots so the air back is not restricted.
