[Advanced PCM cooling technology provides sustained cooling!] The cooling pad of this backpack uses phase change material (PCM gel) adopted by NASA technology. When the ambient temperature rises, it absorbs heat and changes phase from solid to liquid, lowering the temperature, and when it is below 28°C, it naturally freezes and stores the cooling effect, providing a sustained cool feeling on the back when worn. This product is perfect for keeping your back cool and comfortable in hot seasons. It is useful for preventing heatstroke and heatstroke, and reduces discomfort when going out for long periods of time or commuting to work or school.
