Persistent Cooling with the Latest PCM Cooling Technology: Reduces back sweat as a cooling pad for backpacks during summer outings, commutes, school trips, and shopping. Phase change material (PCM gel) adopted from NASA technology freezes naturally below 28°C, achieving continuous cooling when combined with a cool backpack. Keeps you cool for 60-90 minutes in an environment of 25-35°C (more energy-efficient than conventional cooling materials). Using the physical phase change principle like "ice that doesn't melt," it keeps your back cool and prevents sweat odor. Safe for use by adults and children. As a heatstroke prevention item, it's designed for safety for both adults and children. Versatile Application for All Scenes: From preventing back sweat during commutes to heatstroke prevention for elementary school students during their commute, cooling during outdoor activities (fishing/fireworks displays), and multi-use for car seats/strollers. When attached to a backpack, it functions as a cooling pad; when removed, it quickly transforms into a cool cushion or cooling pillow. It shuts out the heat on your child's back during their commute, preventing heatstroke with natural cooling that eliminates the risk of frostbite. A multi-use design that balances cooling effects and heat countermeasures. Ergonomic × Lightweight Design: Optimized 22 x 28 cm size for backpacks (compatible with all types from school bags to outdoor backpacks). 3D shape that fits the back for a cool, close fit. Ergonomic back fit shape + independent filling structure maintains a flat fit even after repeated use. Ultra-lightweight design of 6mm thickness and 190g (50% smaller than conventional products) for excellent storage. Back pad with ventilation holes promotes cool air circulation, preventing condensation and improving breathability. Adjustable clips for easy installation in 10 seconds, even for children. High-Quality Materials for Safe and Lasting Use: Uses German-made biodegradable PCM (TÜV biodegradation certification). 3-layer barrier structure completely prevents frost and condensation. Passes a pressure resistance test 3 times (30,000 cycles) the JIS S 4057 standard. Medical device-level flexible TPU material freezes naturally below 28°C. ❤️ I have many other wonderful products for sale too ♡ ↓ Further discounts are available for bulk purchases (=^x^=)↓ #SHOPEN Management Number: 704-$$880 Genki 【2025】 Backpack Cooling Pad, Cooling Pad, Backpack, Cool Contact, Cooling Pad for Backpack, Backpack Ice Pack, Back, Commuting, School, School Bag, Heatstroke Prevention, Cooling Sheet, Summer, Adults, Elementary School Students, Children (Light Blue)
