What are the Best Male Incontinence Briefs?

My father is 87 years old, has Alzheimer’s, his mobility is poor, and he is incontinent. We’ve been using Depend briefs for about a year, but they’re not doing the job. I’m not sure if it’s the volume of urine or how his penis is positioned in the brief, but every morning we find him laying in a puddle. Does anyone know of a better product or practical solution for this issues? Thanks!
