I like to hike in long pants. Go figure. So, anyhoo, usually one pair of pants is soaked with sweat at the end of the day and I rinse those out and them hang up to dry. I put the other dry pair on. Also, sometimes it rains (I live in the great Pacific Northwest). Once I hit camp I take the wet pair off and put the dry pair on.
