I tested these in the Rockies this summer. They were great until a bear woke me from the tent. They now have a slight slash on the thigh but I'm still going to wear them. I doubt the warranty covers bear slash.

I would buy them again for the comfort and warmth.

Update 12/11/12: I just bought a second pair in the blue, medium. I have a 33" inseam and they are fantastic!
