i use a baseball belt. its made of elastic so i can pull them down to where i want and they'll stay. works very well. i always sag and my pants never fall down
You cant just cut a hole, put some string through it and think its going to hold up. Go to walmart and get some suspenders with some really strong alligator clamps. orjust get the clamps and make them yourself.
You can't just rig through a loop in the front and back. I used some Value Village suspenders and then attached/extended them to my pants with old climbing cord. It goes through every belt loop and works really well. Plus I can adjust my sag for pow days.
