Summarizing and solving the concerns of the site and the managers. The wearable solution "Cómodo gear."

The "Comodo gear i3" is a cooling device that provides comfort. By wearing it around the neck, it achieves a cooling effect in high-temperature environments while maintaining user mobility and work efficiency. It is a wearable air conditioner that incorporates a thermo module, allowing it to cool or warm the neck directly. Users can feel the coolness or warmth at the back of the neck, and by efficiently cooling or heating three points, it quickly provides heating and cooling effects. Compared to commercially available air-cooled neck coolers, the adoption of a water-cooled system achieves high heat dissipation capability. It powerfully and swiftly cools the neck, offering a genuine cooling effect that air-cooled systems cannot provide. The neck size is available in two sizes, S and L, and features an adjustable system that allows users to slide the included magnet to adjust the belt length, accommodating various neck sizes. It can be used by a wide range of individuals, regardless of age or gender. *For more details, please download the PDF or feel free to contact us.

Detailed information

A wearable device that efficiently cools and heats the body by targeting the carotid artery in three specific areas. It directly targets the carotid artery in the neck, which is effective for heat management. It can be used in cooling mode during hot weather and in warming mode during cold weather, allowing you to carry it year-round and stay comfortable according to your needs.
<Water cooling system's heat dissipation capability surpassing air cooling> The product is equipped with high-quality Peltier elements, and the neck section is connected to the main body controller via a tube. Cooling water flows through the tube, and the radiator and fan built into the main body controller circulate the cooling water to cool the Peltier elements. By adopting water cooling instead of air cooling, it is able to achieve a higher cooling capacity.
You can choose sizes S and L.
