I have the Arb Glads from TreeStuff and I don't think I will ever have to shop for pants again. My opinon on the coolness is below 70f no problem and over that just a tad warm but bareable. If I get mud on them I just hose em off, no water has gotten through. Climbing in them is a sinch. And then the fact that your protected from the mighty saw, well...
I knocked over an ol' lady for mine, what will you do for yours?
