Ice Japan Long-Lasting Coolness! Muroran Hyakkoi Mat with Dedicated Cover

Introducing the Muroran Hyakkoi Mat, a cooling mat that can be used without freezing in the freezer, now with a cool-touch fabric cover.
The main unit is designed with a temperature set to 29°C to provide comfortable sleep without overcooling your body. It utilizes the same cooling technology control adopted by JAXA to ensure the cool, comfortable temperature lasts for a long time.
The cooling material inside the main unit gradually absorbs body heat and liquefies, allowing the coolness to last. It can also be solidified again at room temperature (0-29°C) without freezing, making it reusable.
The main unit is manufactured entirely at our company's own factory in Muroran.
A key feature is that it doesn't freeze in the freezer, so the cooling agent melts less and causes less condensation.
It's less likely to wet your head or clothes, so you can place 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 is machine washable at home, ensuring hygienic use.
