[Fully Non-Iron x 3D Pattern] New Additions to the 'i-Polo' Series Changing the Common Sense of Business Wear!

Haruyama Trading Co., Ltd. (Headquarters: Okayama City, Okayama Prefecture, Chairman and President: Masafumi Haruyama), which supports the health of business professionals, will release three new models of the 'i-Polo' series—high-function business polo shirts utilizing the technology of the fully non-iron shirt 'i-Shirt' (*2), which boasts a cumulative sales record of 11 million units (*1)—nationwide at Haruyama stores starting Saturday, April 25, 2026.

As summer heat intensifies year by year and office casual becomes more prevalent, the demand for polo shirts as summer business wear is increasing. On the other hand, many business professionals struggle with issues such as 'collars losing their shape' and 'looking too casual.'

Leveraging our extensive knowledge of suit manufacturing, this series adopts a 3D pattern that contours to the human posture and a 'stand-up collar' similar to dress shirts. This achieves a beautiful collar that stands up perfectly even when wearing a jacket and a three-dimensional silhouette that dramatically improves mobility. Furthermore, equipped with the 'i-Shirt's' unique fully non-iron (*2) functionality, it requires no maintenance after washing.

Three Lineups to Choose From Based on Usage Scenes and Preferred Comfort

These new models are developed in three categories, each solving different summer 'discomforts.' The 'Denim-Look Shirt' serves as a perfect starter item for office casual, offering a stylish appearance while reducing heat through xylitol processing. The 'Biosensor® Shirt' features high-breathability material that increases cooling sensation as it absorbs sweat. The 'Dry Cube® Shirt' boasts overwhelming quick-drying properties through special materials, constantly keeping a smooth touch against the skin. All items are treated with an antibacterial and odor-resistant finish (*3) to reduce sweat odor on hot days. By allowing business professionals to go through the day without worrying about sweat from their commute, we support their performance enhancement.
