Sony Electronics has launched the REON POCKET PRO Plus, an innovative wearable device that reinterprets personal climate control. The small, futuristic gadget rests at the base of your neck and offers a tailored solution to fluctuating temperatures in both indoor and outdoor environments.

The Intuitive Design of the Reon Pocket

Designed as part of the “Reon Pocket” series, introduced in Japan in 2019, the Pro Plus model enhances its predecessors’ capabilities with a more effective thermal system and a thoughtfully adjusted neckband for comfortable everyday wear. By integrating a cooling and heating plate directly against your upper back, it modifies your perceived body temperature through a sleek, invisible process.

A Revolution in Wearables

This development marks the evolution of wearables as both functional and aesthetic accessories. The device, by using dual thermo modules, registers both your skin temperature and external conditions. This feature is especially useful when transitioning between environments, like moving from an air-conditioned office to a humid street.

The “Reon Pocket Pro Plus” operates up to fifteen hours on battery in Smart Cool mode and discreetly integrates into various wardrobes with a design that conceals it beneath collars. In public settings, its fanless design ensures quiet functionality, while its extendable airflow vent discreetly releases excess heat.

Creating a Personal Climate Bubble

The device includes a companion app, offering automatic climactic adjustments and personalized settings. A supplemental sensing tag further enhances its adaptability by measuring ambient temperature and humidity away from the body. This context allows the wearable to better respond to changing environmental conditions, providing a truly individualized climate experience. When it reaches the U.S. this summer, reviews will determine its real-world impact.

Kenji Ito, a leading engineer behind the Sony Electronics” project, designed the device to drastically lower local skin temperatures—up to 25°F/14°C. This local adjustment, focusing on an area dense with temperature receptors and rich in blood flow, makes significant thermal comfort possible with minimal energy use.
