this saddle presses my sensitive perineum (numbness occurs).
That stuck out to me. The best saddles I've tried for perineal numbness have been from ISM and Selle SMP. The SMP TRK works best for me by far, though I'd like less padding. (The ISM worked for a while, but I pretty quickly (200 km) developed a saddle sore where my groin hit the 'horns' of the ISM seat I tried out.
I don't
need padding in my shorts on my Selle SMP saddle, but I believe the modern pads do wick moisture. My groin is wet at the end of my rides, but I think it would be much wetter without the pad.
What clothing do you want to ride in? I ask because I'd hate to ride much on something with seems, like standard underwear and or trousers or shorts.
