Strapped Adjustable Evaporative Cooling Vest (KOC-HK005-03 / KE06)

Zero-power eco-friendly evaporative cooling vest featuring heavy-duty side buckle adjustment straps. Utilizes advanced superabsorbent fiber (SAF) core technology to absorb and store water, releasing it slowly through natural evaporation to lower body temperature by 5°C to 8°C for 3 to 6 hours. Requires no batteries, cables, or ice packs—simply submerge in water for 1-2 minutes, wring out, and wear.
