Any cover made of leather of even vinyl will conduct the heat quite well-
So you should be able to have your pick of color/style/price.
I used a product similar to this on my last truck and it was really very nice.
You have to hand stitch it all the way round - as opposed to the hard wired covers - but it is easy and I did mine in 20 minutes ....and with a little care it will look factory perfect.
I'm sure you could find a nicer one than the eBay link I chose- I was just using that a a visual.
