Product Details

Muroran Hyakkoi Mat
Gently cool and comfortable during sleep!!
Includes a dedicated cover
Brand new, unused item
Set of 2

Designed to maintain a comfortable sleep temperature of 29ยฐC without over-chilling the body, this product applies the same cold storage technology control adopted by JAXA. The cool, comfortable temperature lasts for a long time.
The cold storage material inside the main unit gradually absorbs body heat and liquefies, so the coolness lasts longer. It can be reused by solidifying again at room temperature (0-29ยฐC) without freezing. Since it doesn't freeze in the freezer, the cold storage agent is less likely to melt and cause condensation, so there's no worry about wetting your bedding.

[Materials]

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
