    Too small

    This is after ones I ordered previously were too big. There should have been a notation about the size measurement changes.

    Comfy, but rides up a little

    Comfy over all, and the mesh keeps everything in place and aerated, but the cut for me rides up a little. I’m between sizes and I’m not sure what size I am for Negative, and when I tried to look up underwear sizing, the questionnaire wasn’t too helpful starting off asking your jean size; I don’t know my jean size.
