Sony Thermo Technology Inc. will release its latest wearable thermo-device kit REON POCKET 5 today. The fifth-generation model of the REON POCKET series will be newly launched in Singapore, Malaysia, Thailand, Vietnam, and the United Kingdom, in addition to Japan and Hong Kong. REON POCKET 5 (RNPK-5T) can be worn at the back of the neck to cool or warm the body surface directly at the body contact area.

The launch of REON POCKET 5 marks the debut of Sony’s highly anticipated wearable Thermo-device in the Southeast Asian markets. This comes after the resounding success of its predecessor model REON POCKET 4 in Japan and Hong Kong. In Japan, 10,000 units of REON POCKET 4 were sold in 3 days after its launch and sold out after three months. Hong Kong exhibited a similar response with REON POCKET 4 sold out within the same period of time after its launch.

Better cooling, longer battery life

The newly designed REON POCKET 5 features an enlarged thermo-module and newly structured heat dissipation fan which offers improved cooling efficiency and airflow, resulting in up to 1.5 times higher cooling performance[i] compared to the conventional model[ii]. Featuring 5 COOL Levels, the device delivers powerful cooling and runs for up to 1.8 times longer[iii] – for approximately 7.5 hours at COOL Level 4. In addition, the latest REON POCKET 5 functions quietly by reducing operating noise by up to one-fifth[iv], making it convenient to use even in quiet business environments.

Enhanced temperature control with “SMART COOL ⇔ WARM MODE”[v]

The intuitive innovation by Sony features an enhanced “SMART COOL ⇔ WARM MODE” function that intuitively adjusts to the ambient temperature by switching between cool and warm modes automatically, ensuring utmost comfort.

To improve the cooling function of the REON POCKET 5, the REON POCKET TAG is equipped with the latest software that detects direct sunlight[vi], which enables RNPK–5T to quickly adjust to preset temperatures at 33% faster as compared to previous versions of the software5. Featuring 8 sensors, the REON POCKET 5 and REON POCKET TAG deliver the most accurate temperature control and can be used for up to 10 hours[vii] when used in “SMART COOL⇔WARM MODE”.

table for business and casual settings

Sporting two types of air vent covers, the REON POCKET 5 goes well with both business and casual styles. The air vent for business style extends up to the height of the collar, matching the shape of the neck and back, while the other is shorter for casual style to match the low collar, both of which allow for efficient airflow.

Optional Accessories

A new dedicated compact case[viii] designed to fit the REON POCKET device is now available. The new case is lightweight yet offers excellent cushioning to protect the wearable device and accessories from external shocks and can be used to store the device with air vent cover attached. Peripheral items such as REON POCKET TAG, USB cable, and air vent covers can also be stored in the pockets. Compatible models: RNP-1A / RNP-2 / RNP-3 / RNP-4 / RNP-5.


The new REON POCKET 5 will be available in Malaysia from 18 June 2024 with the SRP of RM799.
