Heh.
They are, no joke, originally designed for ranch hands. They're popular with farmers, ranchers, and motorcycle riders. They're kind of the "flagship" Wranglers, and comparable to Levi's 501.
Compared to 501s, the rise (distance from crotch to top of the pants) is slightly higher, the back pockets are slightly higher, they have a zippered fly, more belt loops, more rivets, and the rolled seam is on the outside instead of the inside. They're not really a slim fit, but not relaxed, either. And the foot openings are larger, to accommodate work boots, but not as loose as "boot cut" jeans that were trendy twenty years ago.
So yeah, wannabe cowboys wear them, but you don't have to look like a wannabe cowboy while wearing them.
