Thank you for viewing! ⑅◡̈* ◆ Brand new, unused item ✨ ◆ Ships the same day ✨ ◆ Immediate purchase is welcome ✨ Genki Techno Backpack Cooling Pad, Cooling Pad for Backpacks, Cooling Sheet, Summer, Adults, Elementary School Students, Children (Khaki) 22cm x 28cm ☘️ Continuous Cooling with the Latest PCM Cooling Technology: Reduces back sweat as a cooling pad for backpacks during summer outings, commutes, school, and shopping. Phase change material (PCM gel) adopted from NASA technology freezes naturally below 28°C, and when combined with a cool backpack, it achieves continuous cooling. Keeps you cool for 60-90 minutes in an environment of 25-35°C (more energy-efficient than conventional cooling materials). The physical phase change principle, like "ice that doesn't melt," keeps your back cool and prevents body odor. Safe for use by adults and children. Designed for safety for both adults and children as a heatstroke prevention item. ☘️ Ergonomic × Lightweight Design: Optimized 22 x 28cm size for backpacks (compatible with 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 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 the JIS S 4057 standard's 3x (30,000 times) pressure resistance test. Medical device-level flexible TPU material realizes natural freezing below 28°C (zero risk of frostbite). Color fading rate of less than 0.1% after 1000 washes with uncolored ink technology + antibacterial treatment thoroughly suppresses mold/odor.
