What our customers are saying
★★★★★
"I was skeptical at first. But then they arrived. Now I am impressed and a complete fan. The quality, design, and fit of these underwear is beyond compare. The comfort of not having an elastics waistband is amazing. These are truly my favorite underwear now."
★★★★★
"I love these. I bought four and will buy another set of 10+ (I am not kidding). It's perfect for IBS. Just an overall great product with a great mission. Thank you."
★★★★★
"Not just for people with an IB diagnosis. Some of us have simply been sensitive to the way elastic presses on our tummies for our whole life. I'm fine normally, but when I sit, it makes me nauseous, and I have to jamb a thumb in there to take the pressure off. Or cut the elastic, or whatever else I have to do. Simply buying larger elastic underwear does NOT work. But this brand does work, and surprisingly well."
A Solution Born From Experience
I’m Jack, designer of iB Underwear, and I started this company at age 48 because I have Irritable Bowel Syndrome (IBS) and I need the most comfortable underwear imaginable. Having suffered elastic waistbands my whole life, I understand how clothing can aggravate symptoms like bloating, cramping, and abdominal sensitivity. So, I set out to create the most comfortable men's underwear the world has ever seen, and I'm pretty sure I did.
