I like the Talon Cordura covered seat that replaced the sweaty butt Kubota vinyl seat on my open station M9. A big improvement and no sweaty butt anymore and of course much less expensive. Kubota, for some reason is quite 'proud' of their seats, why, I have no idea.
One thing I do, do and that is, if the open station M9 is sitting outside, I cover the seat with a large plastic trash bag. Keeps the cats off the Cordura and keeps it dry if it rains. I do have a canopy on it but it still gets wet.
