Neck size guide: 30-39cm. 【High-Quality Material & Refreshing, No Condensation】This cool neck ring uses the latest "PCM material". While the temperature of general substances rises with the surrounding humidity, PCM stops at a constant temperature even if the surrounding temperature rises, absorbing heat and maintaining a constant temperature.

The cool neck ring freezes naturally below 28°C and can be used repeatedly anywhere, indoors or outdoors. 【Easy to Use & Long-Lasting Cooling】This cool neck ring can be used simply by putting it around your neck. Also, the neck has the carotid artery, and cooling this area can cool the blood flowing throughout the body, effectively cooling the whole body and preventing heatstroke.

Usable for 60-120 minutes based on an outside temperature of 25-40°C. 【Wide Range of Uses】This cool neck ring is great for golf, jogging, fishing, cycling, camping, driving, watching sports, studying, the office, housework, and work sites. @M90Y21.68
