Sony REON POCKET 4 Wearable Cooler Neck Cooler/Neck Heater with Automatic Cooling, Hot/Cold Function, Lightweight, and Mobile Battery Compatible

【What is REON POCKET?】 REON POCKET is a wearable thermal device that can directly cool or warm the skin surface where it comes into contact with the body. Because it supports both cooling and warming, it can be used in both summer and winter. *REON POCKET is not intended for use as a heatstroke prevention measure. Please refrain from using it in temperatures above 35°C, for extended periods in direct sunlight, or during work or exercise that causes heavy sweating.

【Increased Battery Capacity for Up to Double the Operating Time】 The increased battery capacity allows for up to approximately double the operating time (*1). Even at COOL level 3, it can be used for approximately 7 hours. The battery has been strengthened, and the design has been refreshed, maintaining a more powerful yet compact body. The air intake has been redesigned to allow for more efficient air circulation. Furthermore, by enlarging the heat dissipation mechanism, it achieves up to approximately 1.2 times (*2) the heat absorption performance. *1 Compared to the conventional model RNP-3. Actual operating time may vary depending on usage and environment. *2 When comparing the maximum cooling level heat absorption performance (average heat absorption over 60 minutes of operation) with the conventional model RNP-3. This may vary depending on usage conditions and environment.

[Five sensors detect temperature, humidity, and activity] In addition to the newly installed temperature and humidity sensor, three temperature sensors detect temperature and humidity. Furthermore, an accelerometer detects activity. Based on the information detected by these sensors, smart functions are provided that are appropriate to the situation.

[SMART COOL MODE automatically adjusts the cooling temperature] The cooling temperature is automatically adjusted according to activity, environment, and personal preferences set in advance on the app. The newly installed temperature and humidity sensor in the main unit can detect increases in humidity due to sweat, etc., further improving SMART COOL MODE. Furthermore, by linking with the separately sold REON POCKET TAG (RNPT-1) (*1), the new function SMART COOL⇔WARM MODE, which automatically switches between COOL and WARM, can also be used. (*2) For example, not only in summer, but also when cold and hot are mixed throughout the day during seasonal changes, it automatically adjusts to the changes in the environment. *1 The REON POCKET TAG (RNPT-1) can be purchased as part of the REON POCKET 4 Sensing Kit (RNPK-4T) or separately. It is not included with this product (RNPK-4). *2 The RNP-4 alone only supports SMART COOL MODE (cooling).

[Neckband 3 for a Comfortable Fit] The included dedicated neckband can be adjusted to fit the size and angle of your neck. The cooling/heating surface of the REON POCKET makes firm contact, providing a stable fit that prevents the device from shifting even when you move. It accommodates a wide range of neck sizes from 34cm to 46cm. The newly designed band has a structure that combines the flexibility to be freely adjusted with the holding power to firmly hold it in place. The adjustable mechanical flexible tube, shape-retaining wire frame, and silicone rubber covering them provide a gentle feel against the skin that is comfortable even when worn for long periods of time. Even when wearing collared clothing, the included airflow parts promote heat dissipation effectively, making exhaust less noticeable.
