Aenergy IN Skirt Women. An insulated skirt for versatile wear. By way of a side zipper, the skirt is pulled on over the ski touring pants without having to take these off. Stretch inserts provide extra freedom of movement. The Aenergy IN Skirt Women benefits from lightweight, high-quality materials such as Pertex Quantum and Primaloft. When needed, it can be stowed away in the integrated pocket. Perfect for those particular cold moments.
