The key components of the Brazilian Jiu Jitsu Uniform
Your uniform is more than just clothing on the mat. It's your armor, a tool for grappling, and a symbol of your journey. Knowing the purpose of each piece is key to staying comfortable, safe, and compliant.
The Gi (Kimono)

- •Jacket weaves: Single, Pearl, or Gold weave for different durability levels
- •IBJJF Rules: Solid white, royal blue, or black only
- •Strict fit requirements to prevent competitive advantages
Gi Belt
The colored belt that signifies your rank and experience level in Brazilian Jiu-Jitsu.

The Chaos of BJJ Uniform Sizing
Different brands have wildly different fits and measurement scales for both gi and no-gi clothing. What fits perfectly from one brand might be too tight or too loose from another.
The Problem
Finding the right BJJ uniform size is notoriously difficult. Every brand seems to have its own sizing system, making it nearly impossible to know what will actually fit your body. What works perfectly from one manufacturer could be uncomfortably tight or frustratingly loose from another.
This sizing inconsistency has become a major pain point in the BJJ community. Just check out what people are saying on Reddit - practitioners everywhere struggle with the same frustrating experience of trial and error, returns, and uncertainty when shopping for uniforms.
