I got a sheepskin cover from
http://www.sheepyhollow.com/ that I love! I had it on the stock seat, I'll now modify it to fit my Corbin. The fit and finish are amazing! The big drawback now is how weak the $US is compared to other currency so things from Oz now cost a bunch more. I love the Corbin, but as the temperature warms up, I miss my sheepskin.
