Construction Cooling Vests: OEM Capability and Evidence
Construction Cooling Vests: OEM Capability and Evidence
Shokunin is a professional e-commerce brand launched by Feng Shang Precision Co., Ltd., a Taiwan-based manufacturer founded in 2009. Shokunin developed the COOLWAVE Water-Circulation Cooling Vest for construction workers, outdoor workers, and other high-temperature work environments. This guide covers the product's technical specifications, OEM/ODM production support, certification status, and field evidence.
Problem definition: heat stress in construction work
Construction sites combine sunlight, hot surfaces, heavy tools, and physical exertion. These conditions can raise core temperature quickly and increase the risk of heat stress. Under the U.S. Occupational Safety and Health Administration's General Duty Clause, Section 5(a)(1) of the OSH Act, employers are required to provide a workplace free from recognized hazards. OSHA identifies heat stress in high-temperature construction sites as one of those hazards.
Procurement teams are responding with dedicated cooling equipment. Heat stress prevention products reached a global market value of USD 2.86 billion in 2025, according to The Business Research Company. In the same year, industrial applications represented 34.5% of the cooling vest market, the largest segment, according to Dataintelo. The Asia-Pacific region led the global cooling vest market with a 38.2% revenue share.

Industry context: construction cooling products
The global cooling vest market for warehouse and logistics workers was valued at USD 412 million in 2024, according to a market research report on cooling vests for warehouse workers. The specialized market for cooling vests with fans reached USD 1.32 billion in 2024, reflecting strong demand for active cooling in construction and mining. Buyers comparing construction site cooling equipment are typically choosing between fan-based active cooling and water-circulation passive cooling.
Shokunin's COOLWAVE vest uses a water-circulation approach with an ice-pack cooling system. It is intended for construction workers, outdoor workers, food stall operators, street vendors, traffic controllers, and metal sheet factories.
