Thank you for viewing! (*^▽^*) ⭐️ Price negotiation → Highly welcome ⭐️ First come, first served ⭐️ Initial defect support guarantee ~ Opened once for confirmation ~ Genki Techno Backpack Cooling Pad, Cooling Pad for Backpacks, Cooling Sheet 22cm x 28cm Reduces back sweat as a cooling pad for backpacks during summer outings, commutes, school, and shopping. The 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. It 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. Designed for safety as a heatstroke prevention item for both adults and children. Versatile installation for all scenes: From preventing back sweat during commutes to preventing heatstroke during elementary school commutes, 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, 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. A multi-use design that combines cooling effects and heat countermeasures. 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 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. ❣️ We also have many other wonderful products for sale ^ ^ ↓ You can get further discounts with bulk purchases (*^▽^*) #sora's shop Management number: 30-2208$$580
