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

COSLEAF emerged as a Guangzhou-based sportswear brand during the 2010s. Public records from the China Sport Show list COSLEAF 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 specializing in fitness apparel, indicating 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 explicitly recorded in the China Sport Show exhibitor database rather than inferred from third-party marketplaces.1

The company remains identifiable in a 2026 Guangzhou municipal government statistical inspection list 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. Documented product categories include:

Fitness apparel

The 2019 China Sport Show listing specifically categorised COSLEAF under fitness apparel,1 suggesting 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 focus.1

Based on surviving industry records, COSLEAF is best described as a functional Chinese activewear brand. Its market positioning sits between 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 significant evidence of its commercial presentation, as the exhibition focuses specifically on China’s sporting-goods industry. Its inclusion in the sports, leisure, and fitness-apparel categories demonstrates how COSLEAF positioned itself within the sector.1

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

The word COSLEAF appears to be a constructed brand name. There is insufficient reliable public evidence to confirm that “COS” and “LEAF” have 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 at 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 regions.

The trademark landscape for the COSLEAF name involves multiple entities. A separate U.S. 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 clothing.2

That registration became active on March 24, 2026, with U.S. Registration No. 8186098.3 Consequently, the 2026 U.S. COSLEAF trademark owner should not automatically be assumed to be the same entity behind the historical COSLEAF sports brand.

In the Philippines, a trademark gazette record shows a COSLEAF application associated with Guangzhou Fengtai Information Technology Co., Ltd. for Class 25 goods.4 This suggests that COSLEAF has had activity involving multiple corporate entities and jurisdictions, and a definitive corporate-ownership history would require examination of underlying trademark assignments and Chinese corporate records.

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

However, current domain information indicates that cosleaf.com was newly registered in February 2026 through DropCatch.com 565 LLC.5 The currently registered domain should therefore not be treated as a continuation of the historical COSLEAF company website, and cannot be described as the official corporate site without additional evidence.

2018

COSLEAF is documented by the China Sport Show as a brand of Guangzhou Fengtai Information Technology Co., Ltd., categorised under sports & leisure, specifically apparel and footwear – running & accessories.1

2019

COSLEAF continues to appear in China Sport Show records, described specifically as a fitness-apparel brand and company.1

2024–2025

A COSLEAF trademark associated with Guangzhou Fengtai Information Technology Co., Ltd. appears in Philippine intellectual-property records under Class 25, covering clothing-related goods.4

2025

A separate COSLEAF U.S. trademark application is filed by Guangzhou Caijue Clothing Co., Ltd. for athletic and general clothing.6

2026

The U.S. COSLEAF trademark owned by Guangzhou Caijue Clothing Co., Ltd. becomes registered,3 while Guangzhou Fengtai Information Technology Co., Ltd. remains identifiable in a Guangzhou municipal government list of companies subject to statistical inspection.
