Short Ergonomic Water Circulation Cooling Vest (KOC-HK002 / KE01)

Ergonomic short-cut water circulation cooling vest powered by an ultra-quiet 5V micro-pump and ice-water closed-loop tubing system. The cropped waistline design ensures zero obstruction with work belts, tactical gear, or sitting posture, while circulating chilled water across the chest and back for continuous 3.5 to 6 hours of full-body heat relief.
