I stumbled into a solution for a problem I had. Dicks sells shorts called "Hydro Dry" for about $20.
They look like bike shorts, just a bit shorter. No lining. I use a Terry Touring saddle. No padded shorts required. Anyway, these shorts will fit any body. They are much more flexible than my PI shorts for instance. I wear them with a large shirt (for touring) so I look decent in Restaurants.
These shorts solved a problem for me. I had persistent heat rash in the area which meets the saddle. No cream, no Brooks, no powder seemed to help. I sweat too much and I bike every day. These shorts keep me nice and cool. It is a big difference compared to bike shorts and I have expensive ones.
I tried soap, anti bacterial, Woolite, etc. and nothing got rid of the rash. These shorts are next to having nothing on.
BTW, no good for ladies. My wife tried them also and reports that she needs cotton down there. They are Polyester. I get off the saddle frequently and that seems to work to cool things down.
