I've hiked in my UK and found it comfortable. It was about 5 miles the first time and no problems. The next hike I took was probably 7 or 8 miles and I fell in the creek in about 50 degree weather. I was freezing in my wet t-shirt but my lower half remained warm under the kilt. It dried at a much faster rate than the shirt too. I was very pleased and often wondered how miserable I would've been had I been wearing jeans. The wife isn't wild about me hiking in the kilt so I don't do it often but we do hike a lot and I'll probably do it again, maybe next week in fact while we're on vacation in Gatlinburg.
