Give the Gift of Cool, Comfortable Sleep This Father’s Day: 'Gyokuryo Cool Comforter premiumEX' Launches on Amazon’s Father’s Day Sale

Shinyo Trading Co., Ltd. (Chuo City, Tokyo) will offer its comforter 'Gyokuryo Cool Comforter,' designed to support a comfortable sleeping environment, at a special limited-time price during Amazon’s Father’s Day Sale.

A Gift of Restful Sleep for Those Who Endure the Heat

As temperatures and humidity rise, many people experience disrupted sleep due to discomfort. The Gyokuryo Cool Comforter is engineered not only for an instant cooling sensation upon contact but also to adapt to body temperature changes throughout the night.
It makes an excellent Father’s Day gift—offering the gift of 'comfortable sleep' to help fathers recover from daily fatigue. And while ideal for heat-sensitive dads, this comforter is recommended for anyone seeking better sleep quality.

Long-Lasting Coolness with Proprietary Temperature Control

The product features the newly developed ultra-cooling material 'Gyokuryo BEYOND COOL.'
Temperature-control capsules absorb and release body heat, gently regulating the microclimate inside the comforter.
Unlike typical cooling bedding that offers only a brief chill, this technology supports a comfortable sleep environment for extended periods.
Additionally, the outer fabric has a Q-MAX value of 0.55, delivering an immediate cooling sensation upon touch.

4-Layer Structure for Optimal Comfort

The Gyokuryo Summer Comforter is designed not just for cooling performance but also for overall sleep comfort. Its four-layer construction delivers cooling, moisture-wicking, and a soft, pleasant touch.
This design prevents stuffiness, even during sweaty summer nights, maintaining a fresh and comfortable sleeping experience.

Reversible Design for Three Seasons: Spring, Summer, and Autumn

The Gyokuryo Comforter features a reversible design with a cooling side and a natural-material side.
Use the high-cooling side during peak summer for a refreshing chill, and switch to the natural-fiber side during the rainy season or early autumn for breathable comfort. One comforter delivers long-term versatility.
Combined with its superior moisture absorption and release properties, the 4-layer structure ensures comfort even in humid, sweat-prone seasons.

Crowdfunding Success and Strong Consumer Support

The Gyokuryo Comforter was first launched on the crowdfunding platform Makuake, where it raised a total of ¥7,603,000 in backing. As a cooling comforter backed by thousands of users, it’s set to enhance summer sleep comfort this season.
