Reinventing Men's Basics

We’re reinventing men’s basics with premium fabrics, smart design, and simple shopping.

Our Story Is Your Story

We founded Mack Weldon because we wanted more out of our basics and always questioned how something so essential could be such a pain to buy. Surrounded by a mind-numbing assortment of underwear and socks in the department store, we realized consistent fit and quality became a game of roulette. So we decided to take matters into our own hands.

We started from scratch and developed our own fabrics. We made sure the design process was meticulous so you can count on the fit being the same each time. And we built a world class customer experience. The difference is in the details, so we obsessed over every stitch and seam until we’d reached our definition of perfect.

Fabric Innovation

Our products start with innovative fabrics. Each is unique for a reason and contains a story that goes beyond the machines.

We Are A Lifestyle Brand

From underwear and socks to swimwear and accessories, our products are always designed with purpose and innovation. Our approach is never random and we don't plan on entering new product categories without looking in our drawers and closet to find out what's missing.

Our Factories

Mack Weldon is designed in the heart of NYC with our warehouse and fulfillment center in Massachusetts. Our product is sourced and manufactured in WRAP-certified factories across the globe, including in the U.S., South America, and Asia.

Ethical Manufacturing

WRAP is a non-profit team of social compliance experts dedicated to promoting safe, lawful, humane, and ethical manufacturing around the world. Our factories are ISO-certified with high-quality management systems, ensuring that our products are manufactured responsibly.

We Are Design Innovators

Our design process will always start with the best fabrics, and if we can't find what we need, we'll invent it—like our 18-Hour Jersey. Next comes an intensive process of trial and error to make sure the fit is as close to perfect as possible. All our products have countless blueprints and fittings because we trust our process and know your expectations.
