    TECHNOLOGY

    01PERFECT COOL

    Ultimate coolness that lasts until morning

    Ultimate coolness
    that lasts until morning

    260% cooling!
    Achieving ultimate coolness
    with special cooling fibers

    We developed yarn and fabric from scratch to achieve ultimate coolness.
    With a contact coolness value of 0.524 (q-max maximum heat absorption rate W/cm²), we achieved ultimate coolness.
    *Cooling value of approximately 260% compared to the standard contact coolness (q-max: W/cm²) of 0.2

    Special cooling fiber

    We developed an ultra-fine microfiber yarn consisting of approximately 100 fibers, with a cooling nylon core and even cooler polyethylene around it. This microfiber yarn is intricately woven with nylon and polyurethane yarns using a special technique.

    Space technology PCM provides
    cooling that lasts until morning

    The duvet's fibers are infused with PCM, an innovative cooling technology developed for space suits, encapsulated in microcapsules. While typical cool-touch bedding loses its cooling effect once it reaches heat saturation,
    Perfect Cool restores and maintains its coolness as the body moves away from the duvet during sleep.

    *PCM stands for phase change material.

    Comfortable temperature control

    PCM microcapsules provide sustained cooling while controlling the temperature inside the bed, protecting your body from the cold of air conditioning.

    02PERFECT COMFORT

    Sleep comfortably even
    in humid or hot environments

    Sleep comfortably even
    in humid or hot environments

    A refreshingly cool and
    luxuriously smooth feel against the skin

    If you feel the summer heat, the cool side will keep you comfortable until morning.
    The fabric uses special microfiber to achieve a smooth, soft, and exquisitely comfortable feel.

    Comfortable on humid days with the dry side,
    reversible structure

    During the sweaty rainy season, the dry side of the reversible structure should be against your skin. It absorbs and disperses sweat, keeping you feeling fresh and comfortable.
    It's suitable for the entire uncomfortable season from the rainy season to mid-summer.

    Comfortable sleep without stuffiness

    Both the cool and dry sides absorb and release moisture, creating a sleeping environment that resists stuffiness.

    03PERFECT
    CLEAN

    Thoroughly cleans
    the inside of the comforter

    Thoroughly cleans
    the inside of the comforter

    Thorough cleaning ensures peace of mind
    against dirt and mites
    inside the comforter.

    The insulation uses hydrophilic batting. Since there's a higher chance of mites lurking inside the comforter than on its surface, the highly hydrophilic batting ensures thorough cleaning of its interior.

    Compact storage

    Store it compactly in the included drawstring bag when not in use. It's also easy to carry for outdoor activities.
