I’m Jack, the founder of iB Underwear. At age 48, after a lifetime of dealing with Irritable Bowel Syndrome (IBS), I set out to solve a problem I knew all too well—finding underwear that doesn’t make discomfort worse.

For years, I struggled with tight elastic waistbands that dug into my stomach, made bloating unbearable, and turned everyday wear into a challenge. Frustrated by the lack of options, I decided to create something better: underwear designed specifically for people like me—those who need true comfort without compromise.
