I've been losing allot of weight and was tired of buying new pants every couple of weeks.  These worked great for holding up my pants.  Worse them underneath my shirt over my under shirt.  No longer needed to pull my pants up every day.

The clamps to adjust the length never seem to fully work, they have to be readjusted 2-3 times a day.

One of the clamps in the front came undone and had to be super glued back.

Before I got undershirts when it was against my skin, I would sweat and it ended up giving me a rash in the back.
