Don't want to leak

I have tried all the depend products and put it this way the "protection with tabs" as recommended by this site, leaks every time my bladder is voided. The only thing I have found that does work has me buying Adult-Baby diapers off the internet on some AB/DL kink site for high dollar. It's awkward to say the least, but haven't got worry about being the grocery store and having a sudden golden stream running down my leg. So, my question if Kimberly Clark maker of not just depends can make a baby diaper for the incontinence of a one year old that doesn't leak then why am I have leaks with their adult products?
