Genki Techno Backpack Cooling Pad, Cold Sheet for Backpacks, Summer, Adults, Elementary School Students, Children (Khaki) 22cm x 28cm

?? Latest PCM Cooling Technology for Sustained Cooling: Reduces back stuffiness as a cooling pad for backpacks during summer outings, commutes, school, and shopping. The phase change material (PCM gel) using NASA technology naturally freezes below 28°C and provides sustained cooling when combined with a cool backpack. Keeps you cool for 60-90 minutes in a 25-35°C environment (more energy-efficient than conventional cooling materials). Based on the physical phase change principle of ice that doesn't melt, it keeps your back cool and prevents sweat odor. Safe for adults and children. Designed for heatstroke prevention, safe for both adults and children.

?? Ergonomic x Lightweight Design: Optimized size of 22x28cm for backpacks (fits everything from randoseru to outdoor backpacks). The 3D shape fits your back for a cool, close fit. The ergonomic back-fitting shape + independent filling structure maintains a flat fit even after repeated use. 6mm thick, 190g ultra-lightweight design (50% smaller than conventional products) for excellent storage. The back pad with ventilation holes promotes cool air circulation, preventing condensation and improving breathability. Includes adjustable clips for easy attachment in 10 seconds, even for children.

?? High-Quality Materials for Lasting Safety: Made with German biodegradable PCM (TüV biodegradable certification acquired). 3-layer barrier structure completely prevents frost and condensation. Passed a pressure resistance test 3 times (30,000 times) the JIS S 4057 standard. Medical device-grade flexible TPU material naturally freezes below 28°C (zero risk of frostbite). Uncolored ink technology ensures less than 0.1% color fading after 1000 washes + antibacterial processing thoroughly suppresses mold and odors.
