TECHNOLOGY

01 PERFECT COOL

Extreme coldness that lasts all night

The perfect 4-layer structure provides cooling sensation, moisture absorption cooling sensation, and sustained cooling sensation, ensuring comfort while you sleep.

The highest level of cooling sensation at 260% of the standard value

In pursuit of the ultimate cooling sensation, we developed the yarn and fabric from scratch.
With a cooling sensation value of 0.524 (Q-MAX maximum heat absorption rate w/m²), it provides the ultimate coolness.
One side is ultra-cool and the other side is gently cool with a Q-MAX value of 0.331, providing two different cooling sensations.
You can get a comfortable sleep according to the temperature.

Uniquely developed super cooling fiber

We developed a composite yarn with a core of cooling nylon covered with ultra-cooling polyethylene. Furthermore, by interweaving this composite yarn with nylon and spandex yarn, we have created the ultimate cooling fabric that is highly cooling to the touch and does not lose its functionality through washing.

Achieves maximum temperature drop of -7.7℃

It absorbs moisture while you sleep and effectively converts it into a cooling sensation. This innovative technology keeps you comfortable while you sleep by eliminating stuffiness and providing a cooling sensation.

Experiment with moisture-absorbing cooling ingredients

By adding the moisture-absorbing cooling ingredient to water, it absorbed water and humidity and absorbed heat, lowering the water temperature by 6.8℃.

Space technology PCM used for a cool feeling that lasts all night

The fibers of the comforter contain microencapsulated PCM, an innovative cooling technology developed for space suits. Conventional cooling bedding loses its cooling effect when the absorbed heat becomes saturated.
Perfect Cool restores and maintains the cooling sensation when you turn over in your sleep and separate your body from the futon.

*PCM is an abbreviation for phase change material.

Comfortable temperature control until morning

By covering yourself with a futon, it absorbs body heat, and when you turn over in your sleep, the futon separates from your body and heat is released quickly, controlling your comfort while you sleep.

02 PERFECT COMFORT

In the long, sleepless summer
A piece of comfort

The reversible structure allows you to use it for a long time, providing a light and comfortable fit without stuffiness.

Reversible structure that can be used for a long time from the rainy season to late summer

The popular reversible structure has been further improved. The dry side has a two-layer breathable structure, which maintains the smooth feel while adding a gentle cooling sensation to the touch.
You can choose the level of coolness that suits you best depending on your preferences and the environment.

Thin, light and smooth to the touch for exceptional comfort

The fabric and filling are made from materials that are as light as possible, and the extremely small quilting makes it feel thin and lightweight when you put it on.

Comfortable sleep without stuffiness

Both the cool and dry sides absorb and release moisture, keeping the humidity in the bed from becoming stuffy.

03 PERFECT CLEAN

Wash at home for lasting cleanliness and deodorization

Since it can be easily washed at home, you can thoroughly clean the futon and avoid having to worry about the unpleasant smell of sweat.

Perfect cleanliness without the need for a cover

It can be used without a cover, and there is no need to worry about dirt, mold, dust mites, or other issues inside the futon when it is washed.

Antibacterial, deodorizing

It prevents the growth of odor-causing bacteria and eliminates the unpleasant smell of sweat that builds up while you sleep, keeping you clean every day.

Compact storage

It can be stored compactly in the included drawstring bag when not in use, and is also easy to carry outdoors.

FAQ

Can I do laundry?

Yes, it can be washed at home. Be sure to put it in a laundry net and wash it separately. Please avoid using bleach (chlorine or oxygen-based).

Can it be put in the dryer?

Do not tumble dry. Tumble drying may cause the product to shrink or the material to deteriorate.

How long is the drying time?

It depends on the weather conditions such as temperature, humidity, and wind on that day, but on a sunny summer day, it will dry in about half a day. Choose a day with good conditions for washing and do your laundry.

What colour is it?

It comes in two color schemes: sax blue and light gray. Both colors are light in color.

Do you have special duvet covers?

There is no dedicated duvet cover. As the material is cool to the touch, we recommend using it without a cover.

Is there a front and back side to the duvet?

It has a reversible structure, with the textured side using dry (moisture absorbing and dispersing) fabric and the smooth side using cool (cooling) fabric.

What season should I use my duvet?

Use the dry side against your skin during the humid rainy season when it's difficult to sleep, and the cool side against your skin in the hot summer.

How can you sleep cooler and cooler?

If you use the ``Brain Sleep Mattress Protector Perfect Cool EX'' or ``Brain Sleep Pillow Cover Perfect Cool EX'' together with your duvet, you can sleep even cooler.

How thick is the futon?

It is approximately 1.3cm thick.

Can I use a compression storage bag?

We do not recommend compressing thin summer futons for long periods of time as this can cause them to become worn out. They can be stored compactly in the included drawstring bag.

Do you need air conditioning?

Recently, summers have been extremely hot, with many cases of heatstroke occurring while sleeping, so we recommend using the heater in conjunction with an air conditioner depending on the room temperature.

My room is designed in a way that makes it easy for heat to build up, so I wanted to do something about it and purchased this product.

In the end, I feel like I made a good purchase.

You will only be able to feel the full effects by using this product, pillowcase (Perfect Cool), and sheets (Perfect Cool) in conjunction with an air conditioner.

Be careful not to get too cold. If that happens, try placing a towel blanket over just your abdomen area, which will keep your head cool but keep your core warm.

I want to use Comforter Perfect Cool EX for all my summer needs

When it arrived and I took it out of the bag, I was amazed at how cold it was.
I washed it first, intending to give it a light wash before using it, but wait a sec!
Is it just half as cold? That's what it ended up feeling.
I'm now thinking about buying a new one and using it without washing it.

I was using a Nitori cooling pad that I bought last year. It was good at first, but after a while it wasn't so great. That's when I came across this product from Brain.
It's expensive, so I thought it would be a waste if it didn't work, but I also bought the pillow and it was good so I decided to go ahead and buy it.
It was very good and chilled. My husband liked it too.

It feels cool wherever I touch it, so I can sleep soundly even on hot nights.
