Yin Yang Reversible Jacket

Wen–Wu Dual Layer System

For martial artists, clothing is never just clothing.
It is a continuation of the body — and a reflection of one’s state.

Yet for practitioners of traditional Chinese martial arts —
Changquan, Taichi, Bajiquan, Crane, Southern styles —
there has never been a garment truly designed for both training and daily life.

Most people settle for T-shirts, hoodies, or historical costumes.

We asked a different question:

What if one jacket could hold both movement and stillness?

One Garment. Two States.

This is a fully reversible jacket built on a simple idea:

Wen and Wu are not separate — they are one system.

• Wu (武) — movement, structure, response
• Wen (文) — calmness, cultivation, inner balance

Each side of the jacket represents a different state.

One side features Thorough Loops (通明扣) —
built for movement and training.

The other features Pan Knot (盤扣) —
designed for everyday wear and cultural expression.

Flip the jacket, and you shift your state.

Turn the Jacket. Change the State.

To master martial arts, you first need intense focus and a peaceful mind. Lacing up the loops to clear your mind and recover your sensitivity. The path to spiritual awakening starts from your fingertips.

Untie the loops in just 3 seconds. The "fast-release" feature makes it easy to check out any wound or injury on the body.  It also symbolizes an end of the session, letting go of nerves and intense emotion caused by the training or fighting.

The history of the thorough loops can be traced back to the Ming and Qing Dynasties in China. Back then, only kung fu masters and apprentices would wear clothes with thorough loops. The attire was not only training gear but also proof of their kung fu identity. Some might have noticed that Jing-Wu Martial School used the same loops on their uniforms in the early 1900s.

However, this authentic design has gradually replaced by modernized clothes since the 1930s. Till now, it has nearly become a lost art. 

Built for Movement

Tongbei Cutting System

The energy flow, so-called "Chi" or "Qi", is a critical concept in Chinese martial arts. To make sure the flow is smooth, your kung fu suit should not cause any pause to your movements; otherwise, your moves won't be powerful enough because the energy is blocked.

The cutting on the shoulder is a whole piece of fabric, perfectly connecting the two sleeves to the back. This seamless design provides exceptional stretchability for smooth movement.  

In Chinese martial arts, the flow of power — Jin (勁) — is everything.

If the garment interrupts the body,
the movement breaks.

This jacket uses a traditional Tongbei (通背) cutting structure,
where the fabric extends continuously from the back through the arms.

This creates:

• Greater range of motion
• Smooth energy transfer
• No resistance during strikes or transitions

The kung fu attire moves as you move.

Buttons and knots often break off kung fu movement, while the thorough loops don’t. The loops can distribute and dissolve force applied upon them, eliminating any possible obstacles from the cloth.   

Another downside of buttons is that they could easily become targets. If your enemy punches you on the button, it can hurt you badly because all the force is concentrated on that single spot. 

What about zippers? A zip jacket won't stick to your body as it often puckers, and you'll have to pull it from time to time. It is quite distractive especially when you're training.  

We believe that warriors can be categorized by their bone structure and body shape. There are 5 types of warriors, a hawk, a crane, a dragon, a tiger, and a bear. Before you get the gear, find out your warrior types first: 

The thorough loop jacket brings the martial mindset to life. It’s an everyday ritual that helps reset the chaotic mind.  Armor yourself with the jacket to stay away from all the hustle and bustle!

The founder, Daniel Huang, is a martial artist, kung fu instructor, and also the founder of Fly by Knight Courtyard Hotel, where he used to teach his guests kung fu before COVID.

Daniel found his passion for martial arts when he was a teen. Yet, it was not until he met the grandmaster, Adam Hsu, did he have a huge breakthrough. Hsu not only taught him Long Fist & Baji Quan, but also the philosophy and history of kung fu, including what a real kung fu attire looks like. It was where the journey started.

The purpose of this project is more than reviving a unique kung fu attire. What we really want to do is to promote Chinese martial arts, and how it benefits our body. Join us now and recover your sensitivity through kung fu training!
