About Beijing Chenglong Science & Technology Co., Ltd.

The high-tech product cooling vest developed and produced by our company can effectively cool down by 20 degrees Celsius. This product is light-weight and comfortable to wear, and can intelligently adjust the temperature based on the environmental temperature. This product is environment-friendly, no need for electricity and ice, no skin irritation. This product is a composite structure of multiple materials, cooled by the use of an intelligent polymer cooling material in the interlayer. After encountering water, this material will automatically undergo physical changes, which can significantly reduce its own temperature, thereby achieving the effect of cooling the protected object. This material can simultaneously trap a large amount of water and promote further evaporation of water molecules, thereby to maintain a low temperature. The usage method is simple, just soak the vest in clean water, twist and wear it on the underwear. It can keep cool for 2-3 hours before soaking it in water to recycle utilization. The weight of the vest is about 300 grams, without any sense of weight bearing. This product is widely used in many outdoor high-temperature operation fields such as military, police, environmental sanitation, epidemic prevention, urban management, security, transportation, construction, power, etc.
