Newly developed proprietary material
MEDIC RECOVERY FIBER
A blend of several carefully selected ceramics at the nano level. Through a unique process, we successfully kneaded high-concentration ceramics into the fabric. Furthermore, the special yarn shape achieves a high far-infrared radiant heat effect.
Far-infrared radiant heat from
MEDIC RECOVERY FIBER
Yarn and fabric were developed from scratch with recovery in mind. This technology effectively absorbs body temperature and radiates it back to the body as far-infrared rays.

Focused warming of the abdomen,
the body's core
Many organs are concentrated around the abdomen and pelvis; warming the abdomen activates internal organ function. A hara-maki is effective for warming a cold abdomen while sleeping and protecting it from cold air from air conditioning during sleep.

Sleep Core Compression

Supervision Points
Applying moderate compression to the diaphragm helps the ribs descend. This also stimulates the abdominal muscles, further aiding rib descent. As a result, the diaphragm relaxes and exhalation becomes easier. This can also lead to full-body relaxation, improved sleep quality, brain rest, and overall body maintenance.

Perfect temperature! Reassuring belly warmer
As soon as I started using this belly warmer, I felt like "this might be good." What I particularly liked was that the temperature was just right; it wasn't too hot or too cold, and the comfortable warmth lasted. Thanks to it, I felt comfortable while sleeping and somehow felt like I got a deep sleep. I felt refreshed when I woke up in the morning. I really like the perfect temperature.
The lack of tightness is also a big appeal, allowing me to sleep relaxed. With good length and thickness, it gives a sense of security, embracing the entire abdomen, so I can use it with peace of mind even on nights when I'm concerned about the cold. The fabric is also durable and feels luxurious, so I think I'll be able to use it for a long time.
Male, 30s

I usually don't use belly warmers, but perhaps because my stomach was warm, my morning bathroom trips drastically decreased. Normally, I would go about 4-5 times due to stomach pain, but for the few days I wore this belly warmer, it was only 0-1 times, and I didn't feel any stomach discomfort. The compression felt just right. It kept me warm, but because it's thin, it felt comfortable to wear all day and all night.
Male, 30s

The stress-free, comfortable compression made it so pleasant to wear that I wanted to wear it not only while sleeping but also during the day. Also, the worn area stayed warm, which helped with cold sensitivity, which I was happy about.
Female, 30s

I gave this as a gift to my husband who has a sensitive stomach. Even though he is very thin, he was able to wear it without any problems. His stomach gradually warmed up, but there was no stuffiness or excessive heat, maintaining a perfect temperature. He used to spend a long time in the restroom, which often meant I had to wait for him, but that has significantly decreased, which benefits me too!
Female, 30s
This is a belly warmer made with Medic Recovery Fiber, which has far-infrared radiation heat function.
Belly warmers often evoke images of the cold season. However, this time we propose it for maintaining your body during summer. Summers in recent years have been extremely hot, and this period is becoming longer. During this time, various factors can chill the body, such as cold air from air conditioners, temperature differences between indoors and outdoors, and excessive consumption of cold foods. In particular, we believe that a cold abdomen is a common concern for everyone. We propose warming your abdomen by utilizing your sleep time.
In addition, with the supervision of Takashi Onuki, an athletic trainer and breathing consultant, we developed Sleep Core Compression (sleep compression). We hope that this belly warmer, which can maintain your body while you sleep, will become a part of your daily routine.
