So far the best mat i've tried for my foz. I like that it's insulated rather than just air, but it doesn't get hot now that it's getting warmer out. Downsides are that i wish it packed smaller, but i get it's because it's pretty thick and I wish it was made to even out the slant in the car floor, but none of the other options I looked into did either so I just got a cheap packing blanket and put it under at the bottom.
