I wear shorts under a Radlerhose with seat upholstery - which is frowned upon by purists. However, since I take the wheel on the work and there then change into a suit pants and the room to watch the move, and is present at quite other people, I do not confuse with a look at my genitals and / or my bare butt this. Of course, that's the only reason.
One sees the shorts under the Radlerhose not when I've just drawn, and they do not warp during the trip also, what would be extremely uncomfortable. A little slippage is not excluded, but that is not critical. When I was in the rain on the way the parts dry super fast, even on the body. Microfibre hurray.
