Today I discovered a work clothing site for nylon pants and polyester shirts.
Duluth Trading Co. has five (count 'em, 5) styles of nylon pants from lightweight to 6.5 oz..
Prices are very reasonable.
All have crotch gussets and three styles have Spandex for more stretch.
I'm getting a pair with Spandex, likely in the 4+ oz. weight.
