I have sheepskin seat covers on both front seats of my '02. Up here in Vancouver the climate is more on the cooler side so sheepskin does seem to be at home here. Sheepskin is an insulator so even in the summer it will buffer you from the heat, however, it does feel different from upholstery which not everyone likes.

That said, I used a company called Shear Comfort. Don't get a universal cover though. Stick with a Custom or Tailor Made level. The more you pay the quality of the sheepskin is amazing. The Tailor Made sheepskin is buttery soft. Not like the universal stuff that feels like an old itchy sweater.

Can you tell I'm a fan of sheepskin?

PS: if the dog rides in the back seat the Cordura seat covers are the way to go.
