About Us

diëtz was born inspired by the tradition of European immigrants who, in the late 19th century, arrived in southern Brazil to forge a better future. With effort and dedication, they founded their workshop for tailoring, shirtmaking, and men’s underwear, establishing a legacy built on quality and a passion for detail.

Decades later, their descendants decided to take it a step further and transform that heritage into a brand with an international vision. Thus diëtz was born, a contemporary brand that blends tradition and modernity, designed for men who seek style, comfort, and confidence in every garment.

Today, diëtz is present in the United States, Canada, Mexico, and the European Union, establishing itself as a trusted brand that looks to the future with global ambition.

Our mission is clear: to offer men’s underwear and swimwear made with next-generation fabrics—breathable, cool, with shape memory and stretch—that provide comfort, freedom of movement, and a perfect fit, highlighting the essence and attributes of the male anatomy.

At diëtz, we believe elegance begins with the essentials, and that’s why we work every day to serve our customers with garments that combine textile innovation, timeless design, and the reassurance of a brand with roots and a forward-looking vision.

diëtz, your most intimate touch
