Originally purchased the longer version of this skirt for my very active wife, since she felt like this one would be a little too short. Then, during the middle of the summer, I realized she was really hot during her workouts and I suggested we try the knee length one. She agreed, and she loves it! She loves feeling freedom to move in this skirt, while staying covered. I love knowing my wife can run and workout without all the guys ogling at her backside. Simply put, this skirt is the perfect balance of freedom of movement, comfort and modesty.
