I have several sets of tights: a couple pair of wool Protogs tights I've had since the late 70s, and a couple pair of more modern lycra tights. The lycra tights have a chamois. The Protogs tights do not. I just wear some old bike shorts under them when I wear the Protogs. Shorts that have become a little too [ahem] translucent to wear as an outer layer are still good enough to provide a chamois for the wool tights.
