I ran across this American company, Diamond Gusset that makes heavy duty, regular old pants at their factory in Blue Ridge, Georgia. They have a commercial on their website showing how they make their pants and it showcases all these champion ladies in their fantastic fifties manning mega-industrial machines. Tough stuff.
The jeans themselves aren't much my style, though they'd be great for riding a bicycle. (They have a patented "diamond crotch" reinforcement system happening.) They also seem targeted to the rancher, farmer, heavy duty lifestyler. The point is, good for them, I say. Good for them for staying put and keeping these ladies in their jobs.
