China Sport Show records from 2018 and 2019 explicitly list COSLEAF / 科里芙 as a brand of Guangzhou Fengtai Information Technology Co., Ltd., specialising in apparel, footwear, running accessories, and fitness wear 1.

COSLEAF appears to have emerged as a Guangzhou-based sportswear brand during the 2010s. One of the most definitive public records originates from the China Sport Show, where COSLEAF was listed as an exhibitor in 2018. The exhibition database identified the following details:

• Company: 广州烽泰信息科技有限公司
• English company name: cosleaf sports Co.Ltd
• Brand: 科里芙 / COSLEAF
• Industry: Sports & Leisure
• Category: Apparels and footwear – Running & accessories

The company was listed in Guangzhou-related exhibition records with a booth in the sportswear section 1. A subsequent 2019 China Sport Show record again identified COSLEAF as a sports and leisure company specialising in fitness apparel, suggesting continued commercial activity beyond its initial 2018 exhibition appearance 1.

The corporate entity associated with the historical COSLEAF brand is Guangzhou Fengtai Information Technology Co., Ltd. (广州烽泰信息科技有限公司). This connection is not merely inferred from third-party marketplaces but is explicitly recorded in the China Sport Show exhibitor database 1.

The company remains identifiable in a 2026 Guangzhou municipal government statistical inspection list, where Guangzhou Fengtai Information Technology Co., Ltd. appears as an operating entity. However, this does not confirm that its present-day business operations remain centred on COSLEAF apparel.

Historically, COSLEAF was positioned around functional sports clothing rather than conventional fashion apparel. Its documented product categories include:

Fitness apparel

The 2019 China Sport Show listing specifically categorised COSLEAF under fitness apparel 1. This indicates a target consumer base interested in gym training, general fitness, exercise, athletic activities, and casual sportswear.

Running apparel

The 2018 exhibitor record places COSLEAF under “running & accessories”, indicating that running gear was a significant component of its product positioning 1.

Sports clothing and footwear

Exhibition classifications also placed the company under “apparel and footwear”, suggesting a broader athletic-wear proposition rather than a single-product niche 1.

Based on available industry records, COSLEAF is best described as a functional Chinese activewear brand. Its market positioning appears to span professional sportswear, fitness and running apparel, and everyday athleisure. Rather than operating as a luxury fashion label, the brand’s documented identity was strongly connected to exercise, fitness, and performance clothing.

The brand’s presence at the China Sport Show is particularly significant, as the exhibition focuses on China’s sporting goods industry. Its inclusion in the sports, leisure, and fitness apparel categories provides evidence of how COSLEAF presented itself commercially during that period 1.

The English name is COSLEAF, whilst the historical Chinese brand name is 科里芙. China Sport Show records consistently provide both names together 1.

The term COSLEAF appears to be a constructed brand name. There is insufficient reliable public evidence to confirm that “COS” and “LEAF” possess officially documented individual meanings. Consequently, interpretations such as “COS = clothing + LEAF = nature” should not be presented as official brand etymology.

COSLEAF is associated with Guangzhou, Guangdong Province, China. The 2019 exhibition record provides an address in the Panyu District / Guangzhou Higher Education Mega Center area, near Guangdong University of Technology, identifying Guangzhou as the company’s base 1. This places the brand within the broader Guangdong apparel and manufacturing ecosystem, one of China’s major commercial and production hubs.

The trademark landscape for the COSLEAF name presents notable complexities. A separate United States trademark record shows COSLEAF registered in 2026 to Guangzhou Caijue Clothing Co., Ltd., rather than Guangzhou Fengtai Information Technology Co., Ltd. This registration covers Class 25 clothing products, including athletic apparel, yoga pants, sports bras, leggings, sports shoes, and other garments 2.

This US registration became active on 24 March 2026, with Registration No. 8186098 3. This distinction indicates that the 2026 US COSLEAF trademark owner should not automatically be assumed to be the same entity behind the historical COSLEAF sports brand.

Additionally, Philippine trademark gazette records show a COSLEAF application associated with Guangzhou Fengtai Information Technology Co., Ltd. for Class 25 goods 4. Collectively, the trademark history suggests that COSLEAF has involved multiple corporate entities and jurisdictions. Establishing a definitive corporate ownership history would require examination of underlying trademark assignments and Chinese corporate records.

Historically, COSLEAF utilised cosleaf.com as its official website. China Sport Show records from both 2018 and 2019 list this domain 1.

However, the domain status has since changed substantially. Current domain information indicates that cosleaf.com was newly registered in February 2026 through DropCatch.com 565 LLC 5. As a result, the currently registered domain should not be treated as a continuation of the historical COSLEAF company website, nor should it be described as the brand’s official corporate site without further verification.
