Since winter is here I figured I'd post an update. Despite cold temps in VA Beach (down to freezing a few times) these mats continue to hold up and they remain soft and supple in the cold weather. No cracks and I'm really happy I put them in. I'm amazed at how much crap you can bring into a car that vanishes into the OEM fiber mats. With these I can see it all and just shake them out from time to time while it is cold as I'm not dragging out the hose in the cold to wash them down.
