I've switched to Cambium C17 this summer, after going through my third leather saddle in four years..

The Cambium may not be as comfortable as worn leather, but I could ride 100kms (60 miles) wearing regular shorts and underwear. Until, that is, we experienced hot weather (close to 40C/100F), at which point it became seriously uncomfortable after 50kms (30 miles), sweaty pants sticking to the saddle surface.

Lightly padded bike pants appeared to solve the problem, by wicking away the sweat.

The plan is to ride next summer on the Cambium.
