ABOUT AUTHENTIC KLEIN

Sportswear With Tradition, Comfort & Real Quality

Since 1948, Authentic Klein has stood for durable sportswear made with care, experience, and a clear focus on comfort. What started as a small family business in Sonthofen has grown into a European sportswear brand trusted for reliable materials, practical fits, and long-lasting quality.

Tradition You Can Feel

OVER 70 YEARS OF EXPERIENCE

Hans Klein Sportmoden KG was founded in 1948 by Hans Klein in a one-room apartment in Sonthofen, Germany. Over the decades, the company grew steadily, moving into larger premises and later building its own factory with development, pattern-making, and sewing facilities.

Today, Authentic Klein combines this long tradition with modern European production. Our focus has remained the same from the beginning: creating sportswear that is comfortable, reliable, and made to last.

Quality With A Responsible Path

EUROPEAN PRODUCTION

By combining German heritage with European production, Authentic Klein keeps every step closer to the people who make and wear our clothing. Short transport routes, direct quality control, and efficient manufacturing help us create sportswear that is reliable, responsible, and ready for everyday movement.

Sizes That Fit Every Person

MADE FOR EVERY BODY

We believe sportswear should feel good on every body. That is why Authentic Klein offers a wide size range for women and men, including plus sizes, petite sizes, and large sizes.

Our products are available in more than 30 sizes for women and more than 50 sizes for men, helping more people find clothing that fits comfortably and supports everyday movement.
