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 body odor. Safe for use by adults and children. As a heatstroke prevention item, it's designed to be safe for both adults and children. ✨ Versatile for all scenes: Prevents back sweat during commutes and school, cooling for heatstroke prevention, and for outdoor activities (fishing/fireworks displays), and multi-use for car seats/strollers. When attached to a backpack, it functions as a cooling pad, and 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. ✨ Ergonomic x Lightweight Design: Optimized 22 x 28cm size for backpacks (compatible with all types of backpacks, 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 thick 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 attachment in 10 seconds, even for children. ✨ Thorough quality control in Japan: Integrated production at our own factory certified by ISO9001. All products undergo inspection before shipment using a three-dimensional measuring machine. Free exchange for size mismatch, and a 365-day free replacement guarantee in case of liquid leakage.
