I bought the Midway mat, does what it needs to do at a good price.
I keep it in the trunk of the car, figure if I ever break down, get a flat, etc on the side of the road it'll come in handy and I won't have to sit in the dirt. I debated one that doubled as a carrier, but since I don't ever use it beyond going from the car into a range, I figured a hardshell case w/ the range bag worked best...but I if had to trek thru woods, etc. I would have gone with the carrier.
