Seeking ultimate cooling,
we developed yarn and fabric from scratch.

We developed ultra-fine yarn made of approximately 100 fibers, with a core of cooling nylon and a highly cooling polyethylene surrounding it. This ultra-fine yarn was then specially woven with nylon and polyurethane yarns.

Double Cooling Technology : Contact Cooling

Instant coolness
with supreme contact cooling

260% cooling effect! Using our proprietary cooling fiber, it achieves ultimate coolness with a contact cooling value of 0.524, the highest level.

※Approximately 260% cooling value of the standard 0.2 for contact cooling (q-max: W/cm²)

Double Cooling Technology : Moisture-Wicking Cooling

Ultimate moisture-wicking cooling,
up to -7.7℃ with sleeping humidity.

Adopts a special material that lowers temperature by absorbing moisture and sweat generated during sleep, providing effective cooling until morning. Cooling function confirmed to be maintained even after 50 washes.

In experiments, a subject wearing sleepwear was misted with water, simulating sweat, and a thermograph was used to measure surface temperature. The temperature reached 26.3℃, the ideal sleeping environment temperature. (60 mists, approx. 6.5g of water)

Absorbs moisture and
effectively converts it into cooling sensation

Innovative technology that eliminates stuffiness and provides a cooling sensation, ensuring comfort during sleep. In experiments, when a moisture-absorbing ingredient was added to water on the right side, a decrease in water temperature was observed.

Because you wear it every day,
anti-bacterial and anti-odor processing keeps it always clean

The fabric is treated with an anti-bacterial and anti-odor finish to prevent bacterial growth in summer.

High effectiveness and wash durability

With 2.5 times the effectiveness of the anti-bacterial and anti-odor standard (antibacterial activity value of 2.2),
its effect remains unchanged even after 10 washes.

Stress-free with a two-layer fabric structure

The inner surface is smooth with low friction against the skin and is a moisture-wicking cool fabric. The outer surface uses 100% cotton fabric with high moisture absorption, designed to be gentle on the skin and efficiently disperse stuffiness. It is said that people sweat over 500ml during summer sleep, but with highly moisture-wicking fabric, you can sleep comfortably.

Eliminates uncomfortable stuffiness during sleep

Through a combination of highly absorbent and moisture-wicking materials, it absorbs and releases moisture, effectively regulating humidity to keep you comfortable even when you sweat, addressing a major cause of disturbed sleep.

Designed not to constrict the body,
for comfortable sleep

This sleepwear is designed to reduce stress by keeping a comfortable range of motion, with larger armholes and eliminating excessive tightening from elastic or ribbing, ensuring comfort during pre-sleep relaxation and not disturbing tossing and turning during sleep.

Reinforcing the neckline prevents deformation and stretching, maintaining a neat collar.

The hem of the T-shirt features a gentle curve with slits on both sides, creating a refreshing look.

Opaque and resistant to sweat stains
even when worn alone

Thanks to the two-layer fabric design, it's opaque and resistant to sweat stains even when worn alone, making it easy to wear casually and convenient for quick outings.

Sweat Stain Experiment

Even when sprayed with water on the inside, simulating sweat, no stains appeared on the outside.
