There's a lot of history and thoughtful design in these rashguards.

The Kanagawa wave is a traditional Japanese motif strongly associated with martial arts. It represents the connection to nature and the powerful, almost insurmountable forces that arise from natural movement.

It serves as a reminder and tribute to the deep history of martial arts. However, it moves forward, not dwelling in the past, but being open, adaptable, and transformative.

This wave and the principle of natural, flowing movement are abstractly reinterpreted in the overall design of the rashguard.

It is supported by many individual elements that all work together to create something great, just like in a good martial arts school.

The wave symbol in the middle of the back does not arise from nothing, but from the clear, framing structure of the triangle.

Energy without rules and structure leads to chaos; it must be well-thought-out and directed. The lower point of the triangle symbolizes the vision and work of the martial arts school's founder, who set meaningful rules, order, and direction so that everyone who embarks on the path of martial arts can train safely, without injury, and effectively. He gave the impetus to the wave, which now unfolds upwards with the help of everyone who is learning or teaching.

The inscriptions on the arms, "We flow, we crush," allude to the famous Bruce Lee quote: *Empty your mind. Be formless, shapeless, like water. You put water into a bottle, it becomes the bottle. You put it into a teapot, it becomes the teapot. Now water can flow or it can crash. Be water, my friend.* It stands for a martial artist's ability to flexibly adapt to any life situation and to consciously control both softness and hardness.

For Dragon Ball and Last Airbender fans, there are also a few hidden Easter eggs on the rashguard.
