Gradient Blue Instant Cool PCM Neck Ring - 28°C Phase Change Material for Sweat-Free Relief - Ultra-Light 135g Comfort for Sports, Office, and Summer Travel

Product Overview Experience a revolutionary way to stay cool this summer with our PCM Neck Cooler Tube. Designed as a personal air conditioner for your neck, this cooling ring utilizes advanced Phase Change Material (PCM) to provide consistent, soothing relief from high temperatures. Unlike messy ice towels or heavy gel packs, this device remains completely dry, ensuring your clothes and skin stay comfortable. Whether you are working in a non-air-conditioned office, commuting, or enjoying outdoor activities, this lightweight 135g accessory is the perfect solution for instant heat relief. Key Features Smart 28°C Phase Change Technology: The core contains premium PCM that automatically crystallizes when temperatures drop below 28°C (82.4°F). This allows the material to absorb body heat efficiently and provide a constant cooling sensation without freezing your skin. Extended Cooling Duration: Engineered for endurance, a single cooling cycle provides 60 to 120 minutes of continuous temperature relief. The duration depends on ambient conditions, making it reliable for various summer activities. Lightweight & Ergonomic Design: Weighing only 135g, the flexible tube fits perfectly around your neck curves. It is designed to be "weightless" so you can wear it for long periods without feeling tired or restricted. 100% Sweat-Free & Dry: Say goodbye to condensation. The surface of the cooler remains dry during use, meaning no water droplets will wet your collar or skin. It offers a clean and comfortable cooling experience. Durable & Reusable Material: Constructed with high-quality, heat-resistant TPU, this neck ring is built to last. It is durable against wear and tear, offering a sustainable and safe physical method to prevent heatstroke and fatigue.
