^ what he said.
Padded bicycle shorts were a real bonus on my US coast to coast (and back) trip back in 09. As pusher said, I always wear them if I'm gonna be on the bike for more than a couple of hours. Not only do they pad, but good quality ones wick moisture away from all your crevices.
I want to die peacefully in my sleep like my grandfather, not screaming
in terror like his passengers.
