I like them for day use and I find them to be tougher than the wool pants. That being said, in warm weather the Obsidians (thinner than kanabs) are hard to beat for breathability. I find myself wearing the Kanabs or Obsidians much more than the Corrugate's as of late, for three reasons. 1) the wool pants don't smell near as bad after a hard day (or 5) of hiking, sweating, getting wet, etc. 2) the wool pants breathe much better and dry out so much faster once wet from rain, snow or sweat. and 3) the wool pants are head and shoulders more comfortable to me than the guides, but I have thunder thighs and a big ass, maybe the fit just suits me better.. Just my thoughts and YMMV.
