I've been hiking with a skirt now for 4 years. I will never go back to pants and shorts. The ease of going to the bathroom in the bush, the ventilation and the quick baths when crossing streams make a skirt a breeze. They also are lighter and dry more quickly. I use the Nike slam 12" skirt (no shorts underneath of course - that would defeat the purpose.) If it's very cold I put tights on under the skirt. I've even seen some guys hiking with skirts now.
