Gunze will be revamping its traditional men's underwear brand, "YG," starting with the 2014 Spring/Summer collection. The new YG is primarily targeted at men in their 40s, with a minimum age limit of 35 and a maximum age limit of 55.

As a result, Gunze's men's underwear lineup now caters to all ages, with "Body Wild" for men in their 20s to mid-30s and "Grand Fit" for men in their 50s and older.

YG was launched in 1971 and has long been a beloved brand for its 100% cotton basic underwear. However, over the past decade, underwear has become fashionable, causing its market share to decline and limiting its customer base to older consumers. Therefore, starting next spring, the brand will be redesigned, with new colors, patterns, materials, and patterns, rejuvenating the brand to suit men in their 40s. The silhouette will be slimmer than before, and dark-colored boxer briefs will be introduced. As for materials, befitting YG's "cotton" image, the brand will maintain its 100% cotton product line. The company will also launch a functional product line primarily made of synthetic fibers, but all items in this line will contain around 30% cotton. Both lines use loosely twisted American cotton and are treated with antibacterial and deodorizing agents. The products are sold through mass retailers, with a base price of 800 yen. To reduce costs, sewing is done at a factory in Vietnam, and YG will focus on researching materials and patterns by opening a dedicated research studio, the "Comfort Science Lab," at its Miyazu factory in Kyoto on September 1st. Meanwhile, in the women's line, the shorts brand "Touché" will be rebranded into a full-item brand. Targeting women in their 30s, the brand will offer simple and beautiful underwear, bras, and shorts. Products will be divided into four categories: "Mode," "Shape," "Days," and "Intimate." "Mode" pursues functional beauty with a fashionable feel. "Shape" shorts are cut to create a leg-lengthening style. "Days" offers a sporty feel for everyday wear, offering items such as wireless bras and camisoles with cups that are comfortable to wear. "Intimate" offers a collection of individual items such as shorts and underwear, which are its specialty. The products are treated with squalane, collagen, and antibacterial agents to promote "wearable cosmetics." They are sold through mass retailers.
