Transforms hot, restless nights.
TECHNOLOGY
01PERFECT COOL
Ultimate coolness
that lasts throughout the night
The perfect four-layer construction delivers contact cooling, moisture-absorbing cooling, and long-lasting cooling, helping maintain comfort during sleep
Contact cooling
Peak-level coolness at 260% of the standard value
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
Proprietary ultra-cooling fibers
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
Achieves a temperature reduction of up to −7.7°C
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
Experiment on moisture-absorbing cooling components
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
All-night cooling with space technology–derived PCM
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
Comfortable temperature control through the morning
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。
02PERFECT COMFORT
Comfort in a single piece
For long, restless summers
A reversible construction allows extended use, delivering a light feel and comfort without moisture buildup
A reversible design for extended use
From the rainy season through late summer
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
Thin and lightweight
Exceptionally comfortable with a smooth, gentle feel
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.
Comfortable sleep without moisture buildup
Both the cool side and the dry side absorb and release moisture, helping maintain a non-humid sleep environment.
03PERFECT CLEAN
Clean and deodorized with
home laundering
Easy home laundering allows thorough cleaning deep inside the comforter, thus making unpleasant odors from perspiration less likely to remain.
Perfect cleanliness
without the need for a cover
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.
Antibacterial, deodorizing, and odor control
Suppresses the growth of odor-causing bacteria, and reduces unpleasant perspiration odors during sleep,
helping maintain a clean condition day after day.
Compact storage
Stored in the included inner bag for compact storage when not in use, and easy to carry for outdoor use as well.

Can it be tumble dried?
Tumble drying is not recommended.
Using a tumble dryer may cause shrinkage or deterioration of the materials.
How long does it take to dry?
Drying time varies depending on temperature, humidity, and airflow.
On a clear summer day, it typically dries within half a day.
For best results, please choose favorable weather conditions when washing.
What colors are available?
Sax blue and light gray.
Both colors may gradually fade with repeated washing.
Is a specialized comforter cover available?
There is no specialized comforter cover.
As this product incorporates cool-to-the-touch materials, use without a cover is recommended.
Does the comforter have a front and back side?
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.
What is the recommended season of use?
During humid rainy seasons, the dry side is recommended.
During hot summer periods, the cool side can be placed against the skin.
How can I achieve an even cooler sleep?
