Jockey sold the world's first briefs with a Y-seam on the front in Chicago. Underwear makes the exposed area of men's legs reach the limit, and clothing historians think it is as meaningful as a bra. The fashion of underwear makes men have an attitude tendency towards this little dress for the first time. At first, men's underwear only highlighted practicality and health. The fashion industry and gay men have endowed the men's underwear market with colorful styles, including thongs and low-waisted briefs. 1999 Mr. Kang Jiaming, the inventor of Taiwan Province King Style patent pocket underwear, was dissatisfied with the lack of improvement of traditional men's underwear due to underwear factors, so he designed the breathability and comfort of men's underwear based on the characteristics of men's physiological structure. The design of underwear not only has a special scrotum bag to keep the scrotum ventilated and dry, but also can avoid the friction and extrusion between the scrotum and the thigh. Its unique positioning has two basic modes: upward and downward. When the male scrotum is placed in isolation from the penis, the erection of the penis can also be located conveniently. The three openings are not only ventilated and dry, but also super convenient for urinating. In the past, the design of men's underwear only focused on the design of colored fabrics and ignored the physiological characteristics of men, which can be described as an innovative breakthrough.
