What products work best for bowel incontinence?

I need help finding what briefs work best for bowel incontinence. I'm 20 years post surgery and I have Ulcerative Colitis. The colitis started after starting a driving job. I have been threw a bunch of medical tests for tumors and now bowel leakage is a problem. I have to wear protection when traveling. Many breifs I buy leak if I have a urge flow. This has been getting worse and I need better protection. Brian
