Ben I am not one of those hipsters trust me LOL!.
They fit fine with a pair of Patagonia medium weight long underwear with room to tuck in a wool shirt.Mine actually run a bit baggy,and are very comfortable.
In Kansas, I threw a pair of wool mil surps over them for cold morning stands. By mid day it warmed and the Kanabs were fine. I rolled around the dirt with them the rest of the day and then wore them out to dinner. They seem to shed dirt, grass and burrs,and brush off easily.
