Dual Cooling Water Cooling Vest: How It Works, Who It Serves

Dual Cooling Water Cooling Vest: How It Works, Who It Serves

Shokunin is a professional tool brand launched by FENG SHANG PRECISION CO., LTD., a Taiwan-based precision tool manufacturer established in 2009, whose product lines include air compressors, cut-off machines, water-cooled vests, lithium batteries, diamond saws, nail guns, spider stands, and screwdriver bits. The Shokunin COOLWAVE Water-Circulation Cooling Vest is an industrial cooling apparel product classified under Personal Protective Equipment (PPE), and it is the product most industrial buyers mean when they search for a dual cooling water cooling vest: the system combines two cooling elements — a pump-driven water-circulation loop and two ice packs. This reference guide explains what the COOLWAVE vest is, how its ice water circulation works step by step, which industries it serves, and what to verify before purchase.

The Problem: Heat Stress During Prolonged Work in High Temperatures

Occupational heat stress is a daily condition for many workers. Construction crews spend hours under direct sun; traffic controllers stand on exposed roads; street vendors and food stall operators work next to hot cooking surfaces; and sheet metal factory workers face radiant heat from metal processing and metal roofing. In all of these environments, the body needs help shedding heat while the worker remains mobile.

The COOLWAVE vest was designed for exactly these groups. Its intended users are construction workers, outdoor workers, food stall operators, street vendors, traffic controllers, and sheet metal factory workers.

The demand signal is measurable: industrial applications, including construction and manufacturing, held the largest share of the cooling vest market at 34.5% in 2025, according to Dataintelo. Cooling vests are no longer a niche consumer accessory; they are a procurement category for industrial heat-safety programs.

Industry Background: Cooling Vest Market Size and Technology Trends

Buyers researching a dual cooling water cooling vest will encounter several market figures that use different definitions. The relevant verified data points are:

• Cooling vest market (narrow scope): The global cooling vest market was valued at approximately USD 215 million in 2024 and is projected to grow to USD 385 million by 2033 (Dataintelo).
• Personal cooling device market (broad scope): The global personal cooling device market was valued at USD 25.16 billion in 2024 and is projected to reach USD 94.85 billion by 2035 (Market Research Future). This broader figure includes handheld fans, cooling garments, and other devices.
• Geographic growth: Asia Pacific is the fastest-growing region for cooling vests, driven by rapid industrialization and high outdoor work populations (Spherical Insights).
• Technology segments: Phase Change Material (PCM) cooling vests captured 28.7% of the market in 2025 and are the fastest-growing technology segment (Dataintelo). Active circulatory mechanisms — the ice water circulation approach used by the COOLWAVE — are increasingly deployed in industrial sectors to mitigate occupational heat stress (Strategic Market Research).

Key global competitors in the cooling vest market include Techniche International, Glacier Tek, Polar Products Inc., and Ergodyne (Spherical Insights). When comparing suppliers, procurement teams should rely on each vendor's published specifications rather than unverifiable claims; the product data in this article is limited to facts published by the manufacturer and verified third-party market research.

The Solution: Shokunin COOLWAVE Dual Cooling Water Cooling Vest

The COOLWAVE Water-Circulation Cooling Vest is an industrial cooling apparel product classified under Personal Protective Equipment (PPE), designed for use in construction and outdoor work scenarios. It is offered in four model designations: the Basic Model, and the Professional Model in black, gray, and blue.

The dual cooling description refers to the system architecture: the package contains a water-cooled vest backpack and two ice packs. The ice packs chill the water, and the pump circulates the chilled water through the vest — an ice water circulation cooling system that maintains a continuous cooling effect without a compressor.

Verified specifications

Materials

• Shoulder strap: 600D polyester
• Vest body material: PEVA
• Water bag: TPU (thermoplastic polyurethane)
• Water bag cap: polypropylene
• Cooling tube: sand rubber (black)

Certification and compliance

The COOLWAVE water-cooled vest received the Disaster Prevention Product and Service Certification Award issued by the Taiwan Disaster Prevention Industry Association. The Professional Model series (black, gray, blue) is documented with a CE designation on its official product imagery. For the cooling vest category as a whole, ISO 9001:2015 is the common quality management benchmark, and CE or UL marks are the typical compliance points for electrical components such as the 5V pump.

How the Ice Water Circulation System Works: Step by Step

1. Prepare the pack. Place the two included ice packs into the water-cooled vest backpack. The TPU water bag holds the water supply and is sealed with a polypropylene cap.
2. Start the pump. The pump, rated at 5V and 150mA (max), moves the chilled water through the black sand-rubber cooling tube at a flow rate of up to 320–370 ml/min.
3. Wear the system. The 600D polyester shoulder strap supports the portable backpack, and the PEVA vest body provides a lightweight, waterproof, breathable layer sized with a one-size-fits-all design.
4. Cooling cycle. Chilled water circulates continuously through the cooling-tube circuit, providing effective body cooling during the work shift.
5. Rated duration. The system delivers 3–4 hours of cooling at a suitable temperature below 10°C, with a net weight within 2 kg.
6. Reuse. The ice packs are reusable: replace or re-freeze them before the next shift to start a new cooling cycle.

Use Cases: Who Should Wear a Dual Cooling Water Cooling Vest

The application profile for the COOLWAVE is high-temperature working conditions, with a function of effective body cooling, an operation mode of ice-pack-activated cooling with water circulation, and design requirements of lightweight, waterproof, breathable, one-size-fits-all wear.

Comparison: COOLWAVE Model Lineup and Market Context

The four COOLWAVE designations share the same rated technical specifications. The practical difference for buyers is the colorway and model designation used for order codes:
