["High-Purity PVA Cooling Towel — Made of high-purity PVA, it provides instant and lasting coolness through water evaporation.When the wet towel contacts your skin or is exposed to air, water vaporization occurs, absorbing large amounts of heat from your skin's surface,and the more moisture it holds,the better it cools.It absorbs up to 8 times its weight in water—far more than cotton—and locks in moisture without dripping.","Textured Dot Surface for Maximized Cooling Efficiency—What sets our cooling towel apart is its innovative dot-textured surface. This design delivers a triple upgrade to your cooling experience by drastically increasing the evaporative surface area, enhancing air circulation, and reducing direct skin adhesion. It accelerates cooling speed and extends cooling duration by an impressive 30% to 50% compared to smooth, flat towels.","How It Works—Wet the towel, slightly squeeze out excess water until drip-free, and wear it around your neck, forehead, or wrists. As moisture evaporates from the PVA material, it draws heat away from your skin, creating a powerful and sustained cooling effect. The more water the towel holds, the longer and more efficiently it cools.","The Towel Will Naturally Harden When Completely Dry—this is normal and not a defect. This hardened state helps inhibit BAC. growth. When ready for reuse, submerge in water for 3–5 minutes to soften it completely.","To Ensure Your Cooling Towels Maintain Peak Performance and Longevity—Clean by gently rinsing or scrubbing with clean water only to remove sweat and dirt. Avoid using soap or detergent, as these can damage the PVA molecular structure and reduce absorbency.Deep clean and disinfect regularly with a white vinegar solution by adding one part white vinegar to ten parts cold water,then soak the towel for 15 minutes and finally rinse with cold water.Allow to dry in a cool, well-ventilated area. Keep out of direct sunlight to prevent the PVA from yellowing, becoming brittle, or cracking.","Versatile Usage—From sports enthusiasts to busy parents, these neck coolers are a must-have!
