"Wonderful! I would describe these, compared with the single layer option as the merino wool has a slightly heavier weight and thicker fabric that adds a light compression because of the weave. It isn't 2 separate layers sewn together but a thicker layer which is resistant to stretching out because of the natural weave. They stay put at the waist and under the cheeks and offer full coverage. I would say if in between or on border of sizes, size up. I have a long torso so it doesn't come up as high on me, 6 inches below my belly button but that works just great for me. These are AWESOME and I'm getting 2 more now! So comfortable and haven't stretched out while wearing b/c of the weave. I washed them on delicate, cold water and lined dry. They were dry in just a few hours. Just get them :)"
