Went on an 8 mile hike in Hawaii across cooled lava to get to the molten stuff. The lava was full of hidden crevices and lava which looks like you can step on it and it cracks like glass. I got cut up pretty bad on both legs (and arms) especially on the return in the dark. Blood soaked both of my shins on the pants. Not one tear on the pants! Washed them and they're like new. Love the fit and the lower pockets but wish the uppers were deeper. Wear them almost everyday. Climbed San G in them a month ago---perfect weight. And by the way, the lava walk was worth every cut!!!
