Anybody else ever have issues with sizing. I am towards the end of medium of ATN's. I ordered a pack of 12. The size on them say they fit from like 30 somethings to 44. I am smaller than a a 40 or so and they almost don't fit Could it be that I am fatter than I though, or the max size that they say not really how large canthey can go. or am I not seeing the right measurement?
