【New】Cooling Sheet, Cold Sheet, Backpack, School Bag, Heat Relief, Unisex, Kids

【Usage Tip】
For best results, chill in your freezer for 5-10 minutes before use.

【Natural Freezing Below 28°C & Sweat Prevention】
This cooling sheet, designed to prevent backpack stuffiness, utilizes PCM material. It's lighter than water and is a special cooling material that instantly becomes cold. PCM is plant-derived, extracted from palm oil, and naturally freezes at temperatures below 28°C. This backpack cooling pad is lightweight and comfortable for long-term use without fatigue. Since body temperature is typically 35-37°C, it provides a comfortable coolness of about 7°C below body temperature. This cool back pad is not excessively cold like ice, so there's no risk of frostbite and it's gentle on the skin. It's a great heat relief product recommended for those who dislike air conditioners or fans!

【Easy Installation】
Simply attach the backpack back cooling pad using the four fasteners. It uses adjustable elastic straps that can be easily secured by adjusting them to the width of your shoulder straps. If it melts and loses its coolness, simply place it in a cool, air-conditioned space, and it will refreeze and can be reused. If you need to use it quickly, it folds compactly for easy storage in refrigerators or freezers. You can also speed up the cooling process by immersing it in tap water. This backpack cooling pad can be used with various bags such as backpacks, school bags, and tote bags.

【Instant Cooling Pad & Product Features】
This cooling pad for backpacks measures 24cm in height and 30cm in width, weighing 300g. The outer layer is made of TPU (thermoplastic polyurethane), and the inside is filled with PCM (octadecane). It's an ideal product for a cool and comfortable back during hot weather. This special material, referred to as ice that doesn't melt, was developed to help customers enjoy the summer comfortably. It is widely compatible with commercially available backpacks. It also excels as a heatstroke prevention measure and provides a comfortable wearing experience. This back cooling pad is recommended as a heat relief item for children commuting in the scorching sun.
