Thank you for viewing! #mari's product list is here Please read the profile before purchasing ⭐ Continuous cooling with the latest PCM cold sensation technology: Reduces back sweat as a cold sensation pad for backpacks during summer outings, commuting, school, and shopping. Phase change material (PCM gel) adopted from NASA technology freezes naturally below 28°C, achieving continuous cooling in combination 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). 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. Heatstroke prevention goods, safe design for adults and children. Versatile installation for all scenes: From preventing back sweat during commuting 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, 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 measures. 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 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. Safe and durable with high-quality materials: 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). Uncolored ink technology with less than 0.1% color fading after 1000 washes + antibacterial treatment thoroughly suppresses mold/odor. Thorough guarantee of Japanese quality control: Integrated production at our own factory certified by ISO9001. Conducts 100% inspection before shipment using a three-dimensional measuring instrument. Free exchange in case of size mismatch, and a 365-day free replacement guarantee in case of liquid leakage. We promise safe use in all situations with a thorough inspection system based on Japanese quality control standards.
