Prior military/active duty will know what these things are, but for everyone else....
So, in an effort to look professional would you wear these?
Hot tip for the men. Attach them more to the outside of the hip at the top. If you attach them to the inside and they snap loose at the sock, your balls are going to get popped by a giant rubber band. Cim can probably tell us his story about that happening. I know he has one.
