I seriously thought about getting a set. However, I talked to somebody some time back who had them. They are neoprene, the same as a wetsuit, and although they are great with moisture, they can get cut easily like a wetsuit. I was concerned about keys or other sharp objects that routinely end up on the seats during a wheeling or camping run. I ended up on my last rig with some saddle blanket type covers. They lasted well, were cheap, and when they finally tore up, I tossed them for a new set.
