Gunze, under its men's innerwear brand "SEEK," has launched the "SEEK Suit In Steteco," a pair of shorts jointly developed with Isetan Mitsukoshi. "Suit In Steteco" not only uses "Cool Make," a material with excellent cooling properties, but also features a special knit elastic waistband that stretches in three directions (vertically, horizontally, and diagonally). Its slim fit and three-dimensional cut ensure ease of movement and also provide deodorizing properties. "Cool Make" is a Gunze-developed material made from a blend of 40% cupra, 30% polyester, and 30% acetate fiber, which creates a cooling sensation through its moisture-wicking and moisture-releasing properties. It comes in four colors: white, black, light gray, and beige, and is priced at ¥3,465. It's available at Isetan Mitsukoshi stores nationwide and the Mitsukoshi online store. The stores where the product will be available include Isetan stores in Shinjuku Main Store, Tachikawa, Matsudo, Urawa, Sagamihara, Fuchu, Shizuoka, Niigata, JR Kyoto, and JR Osaka, and Mitsukoshi stores in Nihonbashi Main Store, Ginza, Chiba, Sapporo, Sendai, Niigata, Sakae, Hoshigaoka, Hiroshima, Takamatsu, Matsuyama, and Fukuoka.
