How It Works
The vest uses a closed‑loop water circulation system: ice packs are placed inside a backpack, the pump circulates chilled water through tubes integrated into the vest, extracting body heat. The pump is powered by a standard power bank (not included) via USB, but even without the pump, the ice packs provide conductive cooling. The 3‑4 hour duration significantly outperforms typical cooling vests that lose effect after 30 minutes.
Target Industries
- Construction workers
- Outdoor maintenance crews
- Metal sheet factory workers
- Street vendors / night market operators
- Traffic controllers
- Food stall operators
3. Company Strength Analysis
Manufacturing & R&D Capability
With a 1,000 m² facility and an annual capacity of 10,000 units, FENG SHANG PRECISION operates a lean but capable production line. The company employs 5 dedicated R&D engineers, enabling continuous improvement and customization. While the standard MOQ is 10 units (for ODM orders), the company can scale production to 3,000 units per month with lead times of 7–14 days. This agility makes them a reliable partner for both small specialist dealers and larger distributors.
Quality Control
Before shipment, each vest undergoes 100% quality testing, including ice pack leakage prevention. The reinforced TPU water bag and sand rubber tubing are selected for durability. The company offers a 6‑month warranty on the water‑cooled vest, underscoring confidence in product reliability.
Certifications & Patents
The COOLWAVE vest is protected by Taiwan Patent No. I886033 (valid until 2044). It has also received the Disaster Prevention Product and Service Certification Award from the Taiwan Disaster Prevention Industry Association, a notable endorsement for safety equipment.

4. Market Reputation & Industry Recognition
Shokunin’s COOLWAVE vest has been deployed in real‑world scenarios for over 10 years, with documented case studies spanning construction sites, traffic control, and metal factories. A notable example: a construction contractor ordered 100 units after a trial showed a significant reduction in heat‑related incidents and improved worker comfort. The vest is praised for its passive cooling (no power required once ice packs are frozen), lightweight design (under 2 kg), and adjustable one‑size‑fits‑all fit.

Compared to competing water‑cooled vests that typically last only 30 minutes, the COOLWAVE’s 3‑4 hour runtime is a standout advantage. Users also report less maintenance due to durable fabric and reusable ice packs, unlike competitors that require frequent ice pack replacement and suffer from higher wear.

Its proven field performance, patent protection, and solid manufacturing backing make it a low‑risk, high‑value procurement choice.
6. Frequently Asked Questions
Q: Do I need a power bank to operate the vest?
The pump requires a 5V USB power source (e.g., a power bank) to circulate water. However, even without the pump, the ice packs provide conductive cooling, though less uniform. For best results, use a small power bank.
Q: How long do the ice packs last?
Each set of two ice packs provides cooling for 3–4 hours in the vest. Spare ice packs can be rotated for continuous use.
Q: Is the vest machine washable?
No. The vest should be wiped clean with a damp cloth. The water bag and tubes can be rinsed separately. Do not submerge the pump.
Q: What is the warranty?
FENG SHANG offers a 6‑month warranty for the water‑cooled vest covering manufacturing defects.
Q: Can I order a sample before bulk purchase?
Yes. Contact the sales team at fsmarketing@fstool.com.tw or WhatsApp +86 18858260055 to discuss sample ordering.
