Onewith Secures Utility Patent For Revolutionary Swimwear Technology

Innovative swimwear brand onewith has been officially granted a utility patent (U.S. Patent No. 12,537,039), securing its proprietary construction method that delivers unmatched comfort and fit, a swimsuit that feels like no-show underwear.

Unlike design patents, which protect appearance, this utility patent protects the functional innovation behind onewith’s raw-cut, elastic-free, dig-free swimwear, setting it apart from traditional and so-called “seamless” swim options.

After more than four years of development and testing, the U.S. Patent and Trademark Office has validated onewith’s unique approach, a bonded, two-layer fabric construction that eliminates traditional seams and elastic. The result is a second-skin feel without digging, rolling, or pressure points.

Crafted with precision, the suits use an ultra-low-profile edge and a flexible inner grip strip to ensure a secure yet gentle hold, offering all-day comfort with modern, flattering aesthetics.

Founded by Hayley Segar, onewith was born out of a gap in the swimwear market, addressing the need for swimwear that fits like undergarments. With this patent, the brand cements its role as a category creator in functional, fashion-forward swimwear innovation.
