OK, I know that these are designed for a certain population demographic, namely, the teens and 20-somethings, and, at 58 yoa, I don't fit in to that group.  But, I wanted a pair of fold-over shorts, and I'm not yet ready to turn my fold-over pants in to shorts.  That said, I like the product.  I use them during my workouts that include Yoga, dance, and kickboxing (not all on the same day) and they are comfortable, although they do "ride up" somewhat.
I plan to use them for as long as I feel like, then carefully dismantle them to use as a pattern for making my own style later.  I haven't been able to find a sewing pattern for fold-over shorts, or I would have gone that route first.
