Why hike in a skirt?  

AIR FLOW!  The more air flow, the less moisture builds up to create chafe.  

Freedom to pee!  You can discreetly squat to pee without pulling down you pants to moon the trail.

Layering is a breeze.  On cold mornings keep you legging on, when you heat up easily pull them off without disrobing. 

Do these skirts have undershorts?
