At Adam Smith Wear, we believe men deserve underwear as versatile and dynamic as their lives. Founded in 2018 by Yasemin De Mirci—a seasoned NYC designer—we spoke to men across the globe and discovered they need comfort, confidence, breathability, support, and reliability in their base layer. So we created Adam Smith: the ideal man who works, trains, socializes, and unwinds in style.

We offer seven distinct collections—Basic, Executive, Sports, For U, Seamless, Relax, and Form—crafted from premium fabrics and tailored to fit every body type and activity. From wrinkle-free executive briefs to breathable performance trunks and bold, date-ready styles, our range moves with you.
