The Modern-Day Shirting Solution

We engineered our proprietary 61 Size system as an off-the-rack solution that delivers a custom-like fit. Over 3 years of R&D, we gathered 5,000+ data points, and developed 1,300+ prototypes to get it just right. Every shirt begins with a sharp, crisp, impeccably crafted collar, and is then matched to multiple sleeve lengths and body. The result? You'll never compromise on fit again.

Redefining the boundaries of cotton, we’ve engineered cotton-based shirting solutions that bridge the divide between comfort and performance. Backed by a robust library of 1,947 patented technologies, we've solved your shirting problems from sweat stains to fabric wrinkles. Our worryfree shirts are designed to be soft, breathable, and functional, to keep up with the demands of your day.

We believe that when it comes to shirts, cotton is superior. We choose Extra-Long Staple (ELS) cotton fibers that are 37-40mm in length, compared to the standard 25mm. This significant difference in fiber length results in a smoother fabric surface with fewer exposed fiber ends. Therefore, our shirts are softer, more resistant to pilling, and can stand the test of multiple wears and washes.

DETERMINANT products are purposefully designed to transition with you from AM to PM. Our wardrobe essentials are constructed with clean lines, modern cuts, and complementary colors to enable effortless mix-and-matching. Whether you need to command attention in the boardroom, or stay polished from field visit to date night, we provide an adaptable wardrobe solution that keeps pace with your dynamic lifestyle.

We value your time. That’s why our shirts are designed to be low-maintenance and easy to care for, allowing you to spend more time on what matters most. All our shirts are designed to be tossed in the wash. Ditch the ironing. Forget the drycleaners. We are setting a new standard for garment care – smart shirting solutions engineered to simplify your daily routine.
