Our Slimfit Legging is one of our bestsellers and for a reason. They feel like a second skin, the high waist is so comfy and the design is basic but beautiful. Nevertheless, we also received requests to make a thinner version, and of course we responded with the the Slimfit III. The waist and bottom area is still compressed (thicker) to avoid seeing through, but the legs are single knitted. That makes the Slimfit III more suitabe for the real sweaty activities, and even for hot yoga.
