About Us
The Story Behind iB Underwear
I’m Jack, founder of iB Underwear, and I started this company at age 48 because I know firsthand the daily challenges that come with living with Irritable Bowel Syndrome (IBS). Having dealt with IBS my whole life, I understand how difficult it can be to find clothing that doesn’t aggravate symptoms like bloating, cramping, and abdominal sensitivity.
Tired of uncomfortable elastic waistbands and restrictive designs, I set out to create a solution that’s practical, comfortable, and supportive. iB Underwear is designed specifically for people like me—those who want comfort without compromise. All of our underwear feature a uniquely-made drawstring waistband, allowing you to adjust the fit with precision as needed. Our men's underwear come with a horizontal fly for added ease and flexibility. We prioritize soft, breathable materials and ergonomic designs, so you can feel at ease all day.
At iB Underwear, we believe that comfort is key to feeling your best. Whether you have IBS, experience occasional bloating, or just value true comfort, iB Underwear is here for you. Thank you for choosing a brand that understands.
