Sheepskin might be good. The real deal in black or dark brown shouldn't be too hard to find.
You might even be able to slip a little 1" thick memory foam under it.
Memory foam (generic Tempurpedic) is all over ebay.
I wonder about synthetic sheep skin vs. breathability. I dunno.
I hear tell gel readily absorbs ambient temps, and can ride hot or cold, depending.

A little OT - Paul (PES) and I figured out at GA '08 that the Triumph factory issued solo seats apparently shipped with different foams.
His solo seat foam layer is as hard as a chunka chestnut, and mine is very noticeably softer & more
compressible. Real leather would be a great upgrade to it. Maybe one of these days, (if I find another job right quick)
I can't tell a difference in distance vs. butt factor with
a naked solo seat or with my Airhawk on top, so I tend to
leave the Airhawk at home.
