Sony REON POCKET 2 Neck Heater/Neck Warmer/Heat and Cool/Neck Cooler/Mobile Battery Compatible/Wearable Thermo Device

This is a new type of wearable thermo device that directly cools or warms the skin surface where it comes into contact with the device. (This product does not deliver a feeling of cold or warm air.) It can be used in both winter and summer, as it is compatible with both cooling and warming. The cooling function has been further enhanced, with heat absorption performance approximately doubled*. *When comparing maximum cooling level heat absorption performance (average heat absorption over the first 60 minutes) with the previous model RNP-1A. However, this may vary depending on usage and environment. Launch the easy-to-use dedicated smartphone app and switch between COOL/WARM/OFF and adjust the temperature with a single touch. By attaching the REON POCKET around your neck using the dedicated neckband or dedicated innerwear (sold separately), you can easily use it without looking out of place.
