Halglof rugged pants really are about as good as you can get, mine have been worn rock climbing, winter mountaineering, bushcraft, and countless miles of walking.
Bought a pair about 4 years ago, lost some weight, bought another pair, really are as good as everyone sais, and they still look like new!
I have never heard a bad word said about them, and the gaiter thing is great.
All i can say is Buy, Buy, Buy a pair or two! really!
