long-lasting coolness
A new,
innovative summer comforter
is introduced
Adopts a proprietary
air throw construction.
Comfort is maintained
even during extreme heat
comparable to last summer.
When the body surface temperature is approximately 35.8°C
(comparable to the ambient temperature
on an extremely hot day),
covering the body with
the comforter air throw resulted
in a decrease to a comfortable temperature of approximately 21.1°C
ISSUE
Due to the impact of global warming,
record-breaking high temperatures caused by
extreme heat are being updated year after year
In addition, humidity levels have increased by
as much as 15% compared to 20 years ago
Consecutive days of extreme heat
Rising electricity costs from air conditioning
Direct cold air from air conditioning
Differences in preferred comfort temperatures within the household
Large temperature gaps between cooled and non-cooled environments
Sleep discomfort in summer is caused not only by temperature,
but also by humidity
By bringing humidity closer to 50 ± 5%, the uncomfortable,
clammy feeling during sleep can be alleviated
A single comforter helps ease
sleep discomfort this summer

Contact cooling
An exceptional level of coolness is achieved through the use of proprietary, specially developed cooling fibers
Contact cooling
An exceptional level of coolness is achieved through the use of proprietary, specially developed cooling fibers
In pursuit of the ultimate cool-to-the-touch feel, the fibers and fabric were developed from the ground up
With a Q-MAX value of 0.524
(maximum heat absorption rate, W/m²).
This comforter delivers an exceptional cool-to-the-touch sensation
Contact cooling
Proprietary ultra-cooling fibers
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.
Ultimate contact cooling
Ultimate contact cooling
An exceptional level of contact cooling is achieved by efficiently absorbing heat upon contact, creating a distinctly cool sensation.
In thermographic testing, the hand appears red before contact,
while after contact, the color shifts to green, indicating a reduction in surface temperature.
Long-lasting cooling
All-night cooling with space technology–derived PCM
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.
* PCM stands for Phase Change Material, a substance that absorbs and releases heat through phase transitions.
Long-lasting cooling performance
Long-lasting cooling performance
The cooling sensation is restored and maintained as the comforter separates from the body during turning over in sleep.
One side features an ultimate contact cooling fabric, while the other side features a towel-like fabric
Reversible construction
One side features an ultimate contact cooling fabric, while the other side features a towel-like fabric
Reversible construction
During humid seasons such as the rainy period, or times when perspiration is more likely, the towel-like side is recommended.
Made from bamboo-derived rayon, it offers a smooth, dry touch and excellent moisture absorption and release,
supporting comfort in humid conditions.

FAQFrequently asked questions
Is it machine-washable?
Yes. It can be washed at home.
Please place the comforter in a laundry net and wash it separately.
Avoid using bleach, including chlorine-based or oxygen-based bleach.
Can I use a tumble drier?
Tumble drying is not recommended, as it may cause shrinkage or deterioration of the product.
We recommend line drying in the shade.
How long does it take to dry?
Drying time varies depending on weather conditions, temperature, and humidity. On a sunny summer day, it typically dries in about half a day. We recommend washing on a day with good weather.
Is there a specialized comforter cover?
This product is machine-washable at home and features a reversible design, so it can be used without a cover. No cover fasteners are attached
Is there a front and back side?
The comforter has a reversible design, with one side featuring a towel-knit surface and the other a cool-touch surface. Please choose the side according to your preference.
What is the recommended season of use?
The comforter can be used reversibly depending on the season and personal preference. As a guideline, we recommend using the cool-touch side in summer, and the towel-knit side against the skin in spring and autumn.
What is the thickness of the comforter?
It is a lightweight comforter with an approximate thickness of 1 cm.
Can vacuum storage bags be used?
Long-term vacumm storage is not recommended for lightweight summer comforters, as it may cause loss of loft. Please store it compactly in the included storage bag.
Is air conditioning unnecessary when using this product?
As summers in recent years have become extremely hot, we recommend using this product together with air conditioning as a precaution against heat-related illness during sleep.
Please tell me about the available colors.
The comforter is available in two colors: Smoke Blue and Pearl Gray. Both feature soft, subtle tones.
