I've tried them on a couple of cargo shorts I own and they may work depending on how loose your pants or shorts are. I need a waist size of around 36. Due to poor timing when shopping for clothes and not having many options, I have a couple of 38's that need a belt to stay awake. I bought them in hopes that I would no longer need a belt that would bite. I've tried all 3 straps on various shorts I have and either it wasn't enough or it was tugging at the strap loops to work a little. When I tried it on some Floppy Waist 36s that I saved, they seemed to work fine, but then maybe I didn't need them at the time. So if you need a few slots on your belt to keep things from falling off you, it's time to go shopping and try something more appropriate. They only work if you need a little help with them. I will be keeping them as I bought some new shorts that they will be working on and I will donate the ones that ended up being too big.
