I do quite a bit of kilted hiking, except for the coldest winter months up north, I usually hike kilted. For warm weather, a cotton washable kilt: Utilikilt, Amerikilt or Nations kilt. In colder weather I have worn one of my wool kilts, however I concur with the concerns about getting caught up in brambles etc, especially if you are on a lesser traveled trail. If its cool and wet I have worn one of my leather kilts they are also great on windy cool days.
