I have a set of wet okole covers ordered for my truck and will post pictures when they arrive. They're fairly popular here in Hawaii since you can wear wet board shorts on them or muddy clothes from hiking or hunting and not worry about your seats getting destroyed. I paid about $350 with shipping.

I decided to not go with the heated option they offer and will grab some carbon fiber seat heaters off eBay down the road if I decide the neoprene isn't doing it for me in our "winter."
