Achieved the No.1 ranking
in the summer bedding category crowdfunding platform Makuake*
The summer comforter evolves
and makes its debut
*As of March 2024, based on internal research.
This single comforter enables
comfort
even during summers
with record-breaking heat
Powered-up
Triple cooling technology
Advanced Perfect 4-Layer Technology
for Ultimate Summer Sleep Comfort.
An evolved
single comforter that
Transforms hot, restless nights.
The perfect four-layer construction delivers contact cooling, moisture-absorbing cooling, and long-lasting cooling, helping maintain comfort during sleep
Contact cooling
In pursuit of ultimate coolness, yarns and fabrics were developed from the ground up.
With a contact cooling value of 0.524 (Q-MAX: maximum heat absorption rate, W/m²), peak-level coolness is achieved.
One side delivers ultra-high coolness, while the other offers a gentler coolness with a Q-MAX value of 0.331, providing two levels of cooling.
Comfortable sleep can be maintained according to ambient heat.
Contact cooling
A composite yarn was developed with cooling nylon at the core, surrounded by ultra-cooling polyethylene.
By interweaving this composite yarn with nylon and spandex yarns, a fabric was achieved that delivers high contact cooling while maintaining performance without degradation from repeated washing or wear.
NEW
Moisture-absorbing cooling
Moisture generated during sleep is absorbed and efficiently converted into a cooling sensation.
This innovative technology reduces moisture buildup while delivering cooling performance,
helping maintain comfort throughout sleep.
NEW
Moisture-absorbing cooling
When the moisture-absorbing cooling component was placed in water, it absorbed moisture and humidity and generated an endothermic reaction, resulting in a water temperature reduction of 6.8°C.
Long-lasting cooling
PCM, an advanced cooling technology originally developed for space suits, is microencapsulated and integrated into the comforter fibers.
Conventional cooling bedding gradually loses its cooling effect once absorbed heat reaches saturation.
Perfect Cool, however, allows the cooling sensation to recover and continue throughout the night as the body naturally shifts during sleep, causing brief separation between the body and the comforter.
* PCM stands for Phase Change Material, a substance that absorbs and releases heat through phase transitions.
Long-lasting cooling
When in use, the comforter absorbs body heat, and as the body separates from the comforter during turning over, heat is quickly released, helping maintain comfort throughout sleep。
A reversible construction allows extended use, delivering a light feel and comfort without moisture buildup
The popular reversible construction has been further enhanced, with a two-layer breathable structure on the dry side that preserves a smooth, dry feel.
Gentle contact cooling has been added, allowing a comfortable level of coolness to be selected according to preference and environment
By using minimal-weight materials for both the shell and fill, and featuring fine micro-quilting, this comforter delivers an exceptionally thin and lightweight sleeping experience.
Both the cool side and the dry side absorb and release moisture, helping maintain a non-humid sleep environment.
Easy home laundering allows thorough cleaning deep inside the comforter, thus making unpleasant odors from perspiration less likely to remain.
Designed for use without a cover, and regular laundering helps keep the inside of the comforter clean, reducing concerns about dirt, mold, house dust, and mites.
Suppresses the growth of odor-causing bacteria, and reduces unpleasant perspiration odors during sleep,
helping maintain a clean condition day after day.
Stored in the included inner bag for compact storage when not in use, and easy to carry for outdoor use as well.

On a clear summer day, it typically dries within half a day.
For best results, please choose favorable weather conditions when washing.
Sax blue and light gray.
Both colors may gradually fade with repeated washing.
There is no specialized comforter cover.
As this product incorporates cool-to-the-touch materials, use without a cover is recommended.
Yes. The comforter features a reversible construction.
The textured side is the dry side with moisture absorption and diffusion,
while the smooth side is the cool side with contact cooling properties.
During humid rainy seasons, the dry side is recommended.
During hot summer periods, the cool side can be placed against the skin.
