My husband and I developed "Comfy Urine Bag Underwear" because of his serious incontinence problems caused by Prostate Cancer. Our search for available solutions provided us with items that were uncomfortable and unreliable. Our CUBU product will hold up your 500 or 600 ml leg bag securely. It is easy to use and very comfortable. We hope it will give you a better "quality of life".
