ONE BOY, stylized in all capital letters, is a Taiwanese functional apparel brand founded by Yen Wei-ting (é¡ÂçÂÂå»·). The company is known for its focus on outdoor-style jackets, particularly its signature "assault jacket" (). The product is marketed as combining weather resistance with contemporary styling. The company has emphasized the integration of functional fabrics and proprietary material development in later stages of its growth. The company engaged well-known entertainers as brand ambassadors, including Taiwanese actress Puff Kuo, singer Aaron Yan and South Korean actress Park Min-young.
ONE BOY was established around 2008. Founder Yen Wei-ting () began selling clothing online as a teenager, initially operating through internet auction platforms.
In 2013, the company withdrew from the Yahoo online marketplace and launched its own official website, shifting toward direct brand management. During this period, the company identified a market opportunity in Taiwan for affordable outdoor-style jackets, which became its core product category.
Since 2023, media investigations reported that the company had accumulated multiple violations of Taiwan's labor regulations. These included infractions related to labor standards compliance.
In October 2024, One Boy's product marketed as the "Ice Shield Quilt" (å°éÂÂ被) was fined by Taiwan's Fair Trade Commission after advertising claims that it was "the coolest in history" were found to lack sufficient substantiation. The company was fined NT$50,000 for false or misleading advertising.
In January 2025, One Boy faced significant consumer complaints regarding delayed deliveries and refund disputes. Some customers reported waiting more than two months for orders while having already been charged via credit card. Others stated that customer service hotlines were difficult to reach and that responses on social media were slow.
