Redefining Menswear, One Piece at a Time
Mack Weldon began as an extraordinary solution to an everyday problem.
Surrounded by a mind-numbing assortment of underwear in the department store—varying in fit and quality—our founder and CEO Brian Berger started to wonder how something so essential could be such a pain to buy. Thus, our 18-Hour Jersey Boxer Brief was born. Men’s underwear was never the same, again.
In the decade-plus since,
VP of Design Matthew Congdon—who enjoyed successful runs at several world-renowned clothing brands—has used the same solutions-oriented approach to reconceive a full range of menswear staples.
and we don’t stop until we get them right.
From featherlight button-ups to tapered sweatpants, the difference is in the details—
