Shūshin (修身) — The Discipline Within
The 3/5 Shūshin Tee is more than a shirt — it’s a symbol of self-mastery. Inspired by the philosophy of Shūshin, meaning self-cultivation or discipline of the self, this tee represents the quiet strength found in daily choices: early mornings, hard reps, and walking away from comfort when it whispers to stay.
The circular motif behind the samurai is no decoration — it’s the unbroken path of refinement. The warrior depicted here is not fighting others, but confronting himself. Every breath, every decision, every moment is an act of self-discipline.
Woven into this design is the philosophy that true strength begins within:
Control over emotions
Respect for others
Mastery of the self
Continual improvement, one choice at a time
The 3/5 Shūshin Tee is cut from mid-weight cotton, oversized for movement, and structured to handle the demands of real training.
This is not just apparel.
This is the embodiment of discipline — refined into form you can wear.
Shūshin 修身 means self-cultivation — the quiet pursuit of becoming stronger, wiser, and more grounded through discipline. It's not about the exterior. It's about who you are when no one's watching.
True power starts within: in the ability to control your emotions, act with integrity, and grow through discomfort — over and over again.
It’s a daily reminder that who you're becoming matters more than who you've been. Growth over comfort. Integrity over shortcuts. The long path over the easy one.
He stands still, yet speaks volumes. Clad in layered armor, sharpened blade in hand — but his true weapon is restraint. His strength wasn’t forged in battle, but in quiet decisions no one sees.
Early mornings. Silent reps. Walking away from comfort when it whispers to stay. The circular symbol behind him isn’t decoration — it’s the unbroken path of refinement.
He’s not fighting others. He’s confronting himself.
Every day. Every breath. Every decision.
This is not a warrior of war.
This is a warrior of self.
We designed this style to sit away from the body, giving you maximum room to breathe and move, providing comfort for all-day wear and training. Made with a special sweat-wicking, four-way stretch fabric that’s cool to the touch.
This style has a relaxed fit. We recommend getting one size down for a more fitted look.
