What Is a BJJ Gi and Why Does It Matter?
A Brazilian Jiu-Jitsu (BJJ) Gi is more than just a uniform — it is your primary tool on the mat. The right Gi affects your grip, comfort, durability, and even your opponent’s ability to control you. Whether you are a beginner stepping onto the mat for the first time or a seasoned competitor, choosing the right BJJ Gi is a decision worth making carefully.
At Onrox International, we manufacture and supply custom BJJ Gis built for performance, comfort, and longevity. In this guide, we break down everything you need to know before buying.
1. Understand the Gi Weave Types
The weave of your BJJ Gi determines its weight, durability, and breathability. The three most common weave types are:
- Single Weave: Lightweight and breathable. Great for warm climates and beginners. Less durable than heavier options.
- Double Weave: Thicker and more durable. Harder to grip. Ideal for competitive training.
- Pearl Weave: The most popular choice. Offers a balance of durability, weight, and breathability. Used by most competitors worldwide.
2. Choose the Right Size
BJJ Gi sizing typically runs from A0 to A6 for adults and M0 to M4 for kids. Sizing can vary between manufacturers, so always check the specific size chart. A well-fitted Gi should allow full range of motion without excess fabric that your opponent can grab.
3. Consider the Material
Most BJJ Gis are made from 100% cotton or cotton-polyester blends. Pure cotton Gis are comfortable but may shrink after washing. Blended fabrics offer more shape retention and faster drying times. At Onrox International, we use pre-shrunk cotton for consistent sizing.
4. Check Competition Rules
If you plan to compete, check the regulations of your federation. IBJJF rules, for example, specify allowed colors (white, blue, black), patch placement restrictions, and sleeve/pant length requirements. Always confirm your Gi is competition-legal before tournament day.
5. Custom BJJ Gis for Gyms and Teams
If you are a gym owner or team manager, custom-branded Gis create a sense of identity and professionalism. Onrox International offers full custom embroidery, patch placement, and color options for gyms ordering in bulk. Our manufacturing is designed for teams that want quality without compromising on branding.
