Yak's power

A yak is a cow called the "cow of the sky."
They live above 3000m above sea level.
It is 30% warmer than wool and 1.2 times more breathable than cashmere.
The power of cow hair from cows living in cold places is amazing.

If you are concerned about mulesing, don't worry.
The wool and yak that we have been handling at GOOD NIGHT SUIT do not damage the skin of sheep or cows.
It is decorated with hair.

I am having the soft hair removed from the yak's chest area.
10% yak, which is such a valuable fiber,
The remaining 90% of the pajamas are made from bioRe organic cotton.

Yak and cotton come together when they are spun into yarn.
These threads were woven into fabric in Nishiwaki City, Hyogo Prefecture.
The gray fabric is brushed three times with a fine needle.

The biggest appeal of these pajamas is that they are warm and lightweight.
Contrary to the wild appearance of the yak,
It feels soft to the touch.

The thickness of the fabric is not too thick, making it perfect for storing away during the off-season.
Relatively compact compared to winter pajamas that often have stiff fabrics.

Combining the power of yaks that live peacefully in cold Tibet with organic cotton grown robustly in India,
The warmest winter pajamas ever created.

Warmer and more comfortable

As soon as you put it on, you will feel the "warmth retention".
The combination of your own body temperature and the strength of the yak,
My body is getting warmer.

In order to enjoy the warmth without losing it,
The first button is attached to the neck.

"It's cold around the neckline..."
“I think it would be nice if the button could be closed further up.”

I made that voice into a form.

In order for you to enjoy the finest texture even more comfortably,
I sewed the back placket.
This is also the result of valuable feedback from our customers.

sleepy country japan

Do you know the average sleeping time of Japanese people?
``Philip Inc.'' conducts awareness surveys in various fields for people's health.
"Survey on Sleep 2023" was conducted from July 12th to 23rd, 2023.

As a result of receiving responses online from 3,752 people across the country, a surprising fact was discovered.

Quoted from Philip's "Sleep Survey 2023"

The majority, 74%, slept less than 6 hours.
I was shocked as I had slept for 9 hours...

17% of people are satisfied with their sleep quality

Quoted from Philip's "Sleep Survey 2023"

64% of people are not satisfied with their sleep.
The reason is

1st place: Light sleep
2nd place: short sleep time
3rd place: Difficulty sleeping

This sad fact is clear to the world.
According to data released by the Organization for Economic Co-operation and Development (OECD) in 2021,
The average time taken by Japanese people is 7 hours and 22 minutes, which is the lowest among the 30 member countries.
(China 9 hours 1 minute, America 8 hours 51 minutes, France 8 hours 32 minutes)

When looking at men and women, women are overwhelmingly shorter.
This is also confirmed by an OECD study.
A major cause is said to be that women are mostly responsible for housework, childcare, and nursing care.

Dear women, the accumulated housework,
There are many tasks such as preparations for tomorrow,
Are you going to bed late?
Thank you very much for your hard work every day.

Try increasing the number of days each week when you fall asleep early.
That's all for today.
Put on your warm pajamas and turn on the sleep switch.
Please try to sleep.

However, it is not enough to simply increase the amount of sleep you get.
It is necessary to improve the quality of sleep.

Let go of the stress and anxiety caused by work, housework, and childcare.
I took a deep breath as I wrapped myself in my pajamas.
Please affirm yourself today.

And remember that you are taking care of yourself.
If you have time, relax with a decaffeinated tea such as GOOD NIGHT TEA and put your smartphone away and go to bed.

When the quality of sleep improves

・Mental stability・Improvement of productivity・Beauty effect・Obesity prevention・Recovery from stress, improvement of tolerance and memory

More and more good things will happen.

What is good quality sleep?

"Being able to fall asleep smoothly"
"Feeling like you slept deeply"
"Wake up refreshed"

If you can feel even just one thing, wouldn't that be progress?

Pajamas can embrace you no matter who you are.
I'm always waiting for you.
Thank you for your hard work today. Let's stay healthy tomorrow too.

[About bag stitching]
All surfaces that come into contact with the skin are covered with bag stitches.
Bag stitching refers to sewing once outside the finished line and covering the painted area in a bag shape to create a seam allowance.
By hiding it in a bag-like shape, the seam allowance does not touch the skin.
The photo below was taken of the armpit, the side that touches the skin.

[About waist elastic]

We have adopted ``BB waffle elastic'' for the waist elastic, which is a concern for tightening.
"BB waffle rubber" is difficult to bend or turn over,
Made of a softer material that stretches better than regular rubber.

About laundry

Place it in a net and use a neutral detergent (such as Emar) that does not contain fluorescent agents.

Although it is possible to use a weak alkaline detergent (such as Attack), we recommend using a neutral detergent that does not contain fluorescent agents to prevent color fading and ensure long-lasting wear.

Please avoid using a dryer at home or in a coin laundry. This will cause it to shrink.

Gently tap the entire surface with your palm to smooth out any wrinkles, then dry in the shade.
