Ice Japan No-Freezing Muroran Hyakkoi Mat with Exclusive Cooling Cover

Cooling mat Muroran Hyakkoi Pillow Mat that can be used without freezing in the freezer, with a cooling material cover.

The main unit is set to a temperature of 29°C to provide comfortable sleep without overcooling the body. We have applied the same cold storage technology control adopted by JAXA to ensure that the cool and comfortable temperature lasts for a long time.
The cold storage material in the main unit gradually absorbs body heat and liquefies, so the coolness lasts longer. It also re-solidifies at room temperature (0-29°C) without freezing, allowing for repeated use.
The main unit is manufactured entirely at our company's own factory in Muroran.
Since it does not freeze in the freezer, the cold storage agent is less likely to melt and cause condensation, which is a key feature.
It is less likely to wet your head or clothes, so you can use it by placing your head directly on it if you prefer.
The large size prevents it from shifting even when you turn over, and its soft texture is also a highlight.
The dedicated cover can be washed in a household washing machine, so it can be used hygienically (cover made in China).
