To be honest the Soma saddles are junk. They are knock-offs of classic Selle saddles, which are actually coming back into production.

If you ride in jeans suede or leather is not a good choice because the saddles will get stained and never come out.

I have a white Fizik Arione and I can ride in rain in dyed jeans without worry. The synthetic material cleans up nicely and gets clean pretty easily.
