From the Kishu Underwear brand, which debuted in 2018, comes a long-awaited new business-style undergarment.

---

Kishu Underwear, which made its debut in 2018 Isetan Shinjuku Store, Men's Building , is a Japanese-made underwear brand born from the pursuit of "what truly makes comfortable underwear?" from the unique perspective of a knit fabric manufacturer located in Wakayama Prefecture, a region famous for its knitwear production.

All processes, from fabric design, knitting, dyeing, brushing, pattern making, cutting, and sewing, are carried out in Japanese factories. The skilled techniques of experienced craftsmen are utilized in each of these fields.

This short-sleeved V-neck design is suitable for both business and casual occasions, and is designed to be inconspicuous even when the top button of a dress shirt or polo shirt is unbuttoned! This business-oriented version was created at the request of our underwear buyer and is a new model for 2019.
Leveraging the technical expertise unique to a knit fabric manufacturer, this fabric is thinner than conventional Kishu underwear fabrics yet provides excellent warmth, making it ideal for business settings where it won't add bulk when worn as an undershirt with a dress shirt.

 

Despite being lightweight, it retains warmth remarkably well, and above all, its warmth is exceptional. In the city center during winter, you could probably get by with just a light trench coat over a suit during the daytime.

MXP combines Goldwin's accumulated expertise in sportswear functionality, such as ease of movement and sweat-wicking properties, with a basic yet refined design. It also incorporates cutting-edge odor-eliminating technologies, including the odor-eliminating and antibacterial functional material "Maxifresh® Plus." This time, we're introducing the "LUXCELL WARM" series, which uses microfiber to achieve a smooth feel against the skin.

In addition to the far-infrared heat retention effect of Photoelectron® fiber, the use of moisture-absorbing and heat-generating functional yarn makes this garment warm despite its thinness, making it suitable for a wide range of seasons from early autumn to early spring.
The MaxiFresh® function prevents odor caused by sweat and dampness.

This simple crew-neck long-sleeved t-shirt is versatile enough to be worn on its own or as an underlayer. Its lightweight yet warm material makes it perfect for short trips and other occasions where you might need a lighter, more comfortable piece.
