Originally for men, abdominal protection 'Chō-ii Pants' goes unisex following surge in female users; new spats also revealed

The desire to protect one's abdomen knows no gender. LUNDATTE Inc. is expanding its 'Chō-ii Pants,' a high-waisted boxer brief without seams or waist elastic made using special knitting technology possessed by only two companies in Japan, into a unisex line in response to the increase in female users. Furthermore, pre-sales for the new 'Chō-ii Spats,' designed for sports, will begin on Makuake on May 21, 2026.

The genderless wave hits innerwear With an estimated 12 million people suffering from abdominal discomfort, the need to "protect the abdomen" is recognized as a lifestyle issue regardless of gender. "Chō-ii Pants" was born from this simple philosophy. LUNDATTE received increasing inquiries for a women's version, leading to the launch of the unisex line.

Technology that made 'no seams or elastic' possible Instead of sewing parts together, the garment is knitted as a "single structure" from a single bundle of thread. It took three years to commercialize with the cooperation of a 78-year-old established Japanese manufacturer. The design is patent-pending and has received a design patent. It has been recognized by various entities, including winning the Japan Patent Attorneys Association Chairman's Grand Prix.

New product blurring the lines between sports and daily life The 'Chō-ii Spats' were developed for runners and sports enthusiasts. They pursue a natural fit that prevents the abdomen from catching a cold while minimizing constriction.
