A Solution Built From Experience
I’m Jack Wright, founder of iB Underwear. I started this company after years of dealing with discomfort from tight waistbands. I couldn’t find a pair that stayed comfortable all day—so I made one without elastic.
The difference is simple, but you feel it right away.
