What are the three discipline variants?

The Discipline T-Shirts are available in Boxing, Jiu-Jitsu, and Muay Thai variants — each with discipline-specific graphic design celebrating that combat sport. Choose the variant that represents your primary discipline or sport identity. Many practitioners who train multiple disciplines buy more than one.

Is this a training top or primarily a casual tee?

The Discipline T-Shirt is designed primarily as a casual wear and lifestyle piece — wear it to the gym, to tournaments, or as everyday casual wear. The cotton/poly blend does not have the moisture-wicking and quick-dry properties of Hayabusa's compression rash guard range, making it better suited for casual use than as a performance training top.

How does the sizing run?

The Discipline T-Shirt uses an athletic relaxed fit — not overly tight, not boxy. It is a unisex-friendly design that works across different body types. If you prefer a fitted look, sizing down one size from your usual is a common approach. If you prefer more room for casual layering, stick to your standard size. Pre-shrunk construction maintains sizing reliably with cold-wash care.

How do I care for this t-shirt?

Machine wash cold to maintain sizing and colour. Tumble dry on low heat. Do not iron directly on any printed graphic areas. Pre-shrunk construction means cold-wash and low-heat dry is sufficient to maintain the garment size reliably over time.
