[Natural Freezing Below 28°C & Sweat Countermeasure] This cooling sheet/cold sensation sheet for preventing backpack stuffiness uses PCM material, which is lighter than water and a special cold sensation material that instantly cools down. PCM is plant-derived, extracted from palm oil, and naturally freezes at room temperatures below 28°C. This backpack cold sensation pad is lightweight and does not cause fatigue even with prolonged use. Since body temperature is generally 35-37°C, it provides a comfortable coolness of 7°C below body temperature. The cool back pad is not as cold as ice, so there is no risk of frostbite and it is gentle on the skin. It's a great heat relief product recommended for those who dislike air conditioners or fans! [Note] For best results, please chill in the freezer for 5-10 minutes before use.

This backpack back cooling pad keeps your back cool even when wearing a backpack. It's perfect for preventing stuffiness and heat in backpacks and rucksacks. It's not as cold as regular ice, so there's no risk of frostbite, and it can be safely used by both adults and children. It cools down a sweaty body and maintains a comfortable perceived temperature.
