When we exercise, we usually feel discomfort for heat from outside and sweat from body. So we excercise less than what we planned to do. It is not efficient way to exercise and it makes us feel bad.

Using the principle of Cool-gel, it improves the circulation of temperature and maintains body temperature. And with listening to the music and removing inner discomfort, it is bluetooth earphone design that helps people to enjoy sports long time without any discomfort.
Highly enriched compressed gel absorbs the warmth from body and releases heat. So it drops body temperature to certain degree and maintains the pleasant state.
