Elevating Men’s Basics, One Style at a Time. Mack Weldon began as an extraordinary solution to an everyday problem. Surrounded by a mind-numbing assortment of men’s underwear in the department store, our founder and CEO Brian Berger started to wonder how something so fundamental could be such a pain to buy. Thus, our bestselling 18-Hour Jersey Boxer Brief was born.

In the decade-plus since, we’ve used the same solutions-oriented approach to reconcieve a full range of quality men’s essentials. From uniquely breathable t-shirts, to permanently odor-resistant underwear, we obsess over every detail and don’t stop until we get them right. The result: clothes that help you look and feel more comfortable, no matter where your day takes you.
