New, unused item. Will be shipped in simple packaging. Cooling Vest Cool Vest L Ice Harness For use as an inner layer with fan-equipped workwear, etc. Heatstroke prevention goods, all-mesh type Includes 3 ice packs. Photos 9 and 10 are of the actual product. Key Features! ■ All-mesh type specifically designed for inner layers The "Ice Harness Inner" is an all-mesh type specifically designed to be worn as an inner layer under work clothes or suits, providing excellent breathability. It's a heatstroke prevention product that prevents a decrease in work efficiency due to heat stress. ■ Cooling effect UP when used with fan-equipped workwear The all-mesh design significantly improves breathability. When used in conjunction with fan-equipped workwear, the circulating air is cooled, resulting in a synergistic effect and further cooling. The material uses antibacterial and deodorizing fabric. ■ Heatstroke prevention for people working in extreme heat This is a heatstroke prevention product designed for people working in extreme heat. It is useful for outdoor work in the scorching sun. ■ Cools blood flow to prevent body temperature from rising The "Ice Harness" cooling vest is designed to have ice packs placed in three locations: the back and under the armpits. By effectively cooling the armpits, cooled blood flow is sent throughout the body, preventing body temperature from rising. ■ Accurate placement of cooling packs The shoulder straps can be adjusted to accurately position the cooling packs, allowing you to cool the blood flow in the large arteries under the armpits. Conventional products did not have the function to change the position of the cooling packs to fit each person's body shape, so the cooling packs were often placed on the sides of the abdomen, which would cool the internal organs. This shortcoming has been improved, and the focus is on "accurately placing the cooling packs under the armpits." ■ Comfortable to wear and reduces fatigue Because it fits closely to the body, the cooling packs do not dangle, eliminating fatigue and hindering movement. By securing the ice packs in place, drawbacks such as "stiff shoulders" have also been improved. ■ For those required to wear long-sleeved work clothes For heatstroke prevention in workplaces where long-sleeved work clothes/uniforms are required, such as construction sites, agricultural work, warehouse work, and security services. Also useful for fishing, BBQs, camping, gardening, and general outdoor activities. ■ Tested on a human-shaped model in a room with a temperature of 35 degrees Celsius and 80% humidity, It has been verified that the temperature of the contact areas is maintained below 20 degrees Celsius. (From the Industrial Technology Research Institute) Maintains 20 degrees for 6 hours or more. Ships in 1-2 days, excluding Saturdays, Sundays, and holidays.
