Horny Toad Men's Jaywalk Pant 32-Inch Pant, Charcoal, 38
Jaywalk twill subscribes to no traditional rules.  While not exactly a denim, it satisfies that need but on its own terms.  Slub yarns add a slightly random texture to the twill weave, and the color is designed to wash down into a mellowed vintage look.  For making evasive moves, a small dose of spandex adds stretch and mobility.
