I absolutely love my Stephans sheepskin saddle cloth. Its lined with sheepskin just under the top half so you still get the close feel by your legs. They wash really well too, mine still looks brand new after about 3 years of regular use.
I have a shires one that has a fake sheepskin lining its thick but not as thick as the polypads.
I use mine on all the youngsters when breaking for extra comfort on fragile backs. I have had it for a year now and it looks like new.
