During summer commutes, office hours, home routines, and outdoor activities, neck heat, sweat, and stickiness can quickly become uncomfortable. Ordinary cooling neck rings may feel very cold when first worn, but the cooling sensation often fades quickly. Excessive cold stimulation may also not be suitable for long-term wear. The Japan OCRU Dual-Layer PCM Cooling Neck Ring features a dual-temperature structure with an 18°C outer layer and a 28°C inner layer. It gives you an instant cooling sensation first, then continues to maintain a gentle and refreshing feel. ● 18°C Outer Layer｜Instant cooling sensation Ideal for hot outdoor environments, daily commutes, and the moment you step indoors. It quickly delivers a refreshing cooling effect and helps reduce stuffy discomfort around the neck. ● 28°C Inner Layer｜Long-lasting gentle freshness Provides a comfortable cooling feel without excessive cold stimulation, making it suitable for the office, home, commuting, and everyday long-term wear. ● Dual-Layer PCM Design｜Cooling duration upgraded by 1.6× Compared with ordinary single-layer cooling neck rings, the dual-layer PCM structure helps extend the refreshing sensation, so the coolness lasts beyond the first moment. ● No power, no charging｜Reusable after cooling No batteries or charging required. Simply cool it in the refrigerator, freezer, or a low-temperature environment, and it can be used repeatedly with ease. ● Less condensation｜Helps keep clothes and bags dry The surface is less likely to form water droplets, reducing the chance of wetting collars, bags, or tabletops. Comfortable and convenient for commuting and daily outings. Recommended for: Daily commuting, scooter rides, outdoor activities, office use, housework, summer travel, camping, and casual walks. In hot summer weather, cooling should not only feel refreshing at first — it should last.
