What is a Haramaki? The Japanese Core Warmer Explained

Discover the haramaki - Japan's traditional belly warmer, now loved by dancers, yogis, and aerialists. Learn what it is, how to wear it, and who it's for.

If you've ever wished for something that keeps your core warm without restricting movement, you may have already found your answer - you just didn't know its name yet. The haramaki is a Japanese core warmer with centuries of history, and it's quietly becoming a staple for dancers, aerialists, and yogis across Europe. So what exactly is it, and is it right for you?

What Does "Haramaki" Mean?

The word haramaki (腹巻き) comes from Japanese: hara meaning belly or abdomen, and maki meaning wrap. Literally, it's a "belly wrap." Traditionally worn in Japan to protect the stomach from cold and support digestion, the haramaki has evolved into a versatile garment worn by people of all ages - from newborns to the elderly.

What Does a Haramaki Look Like?

A haramaki is a seamless, tube-shaped band worn around the midsection - covering the lower back, kidneys, and abdomen. Unlike a waist trainer or compression band, it has no boning, no waistband, and no fasteners. It simply slips on and stays in place through gentle stretch. Most are made from natural fabrics like cotton or bamboo, making them soft, breathable, and kind to sensitive skin.

Who Wears a Haramaki?

The haramaki has found a devoted following in the movement community:

• Aerialists & pole dancers - keeps the lower back warm between climbs without adding bulk
• Dancers & contemporary movers - worn over or under a leotard for core warmth during cold studio sessions
• Yogis & pilates practitioners - supports the kidneys and digestive organs during floor work
• Anyone with back sensitivity - a gentle, non-compressive alternative to back braces or waist bands

Why Natural Fabric Matters

Many haramaki on the market are made from fully synthetic blends. At Fly and Fit, ours are crafted from 95% cotton and 5% elastane - a composition we chose deliberately. The high cotton content keeps the fabric breathable, soft against skin, and comfortable during long training sessions, while the elastane gives it just enough stretch to move with your body and hold its shape over time. Natural where it counts, functional where it needs to be.

How to Wear a Haramaki

Simply step into it or pull it over your head and position it around your midsection. It can be worn:

• Under your training clothes for invisible warmth
• Over a leotard or crop top as a visible layer
• Layered with a second haramaki for extra warmth in cold studios
