Do BJJ Gis Come With a White Belt and What to Expect
While you’ll often find a belt tucked inside the gi bag, these complimentary belts are usually basic, thin, and mass-produced. They serve the immediate purpose of holding your gi closed during your first few classes. As you progress, you’ll likely want to replace that starter belt with a more durable option that holds a knot securely during intense sparring sessions.
What is the standard sizing convention for Brazilian Jiu-Jitsu uniforms?
Standard gi sizing uses an alphanumeric system ranging from A0 to A5, where the letter denotes the cut and the number indicates height and weight. An A2 size typically fits individuals between 5'7" and 5'10" weighing roughly 150 to 180 pounds, though brands vary significantly in their specific measurements.

How should a beginner determine the correct size of a gi?
To find the right fit, consult the manufacturer's size chart by measuring your height, weight, and arm span against their provided data. Look for a balance where the sleeves reach your wrist bone without being overly baggy, as excess fabric allows opponents to secure grips more easily. A lot of people assume that buying a larger size allows room for shrinkage, but modern high-end gis are often pre-shrunk, meaning an oversized purchase will likely remain too loose and cumbersome for effective training, hindering your movement on the mats.
What are the primary differences between single, double, and gold weave fabrics?
Single weaves are lightweight and breathable, usually weighing around 350 to 450 grams per square meter. Double weaves are much heavier and thicker, providing durability at the cost of heat retention, while gold weaves offer a middle ground by combining the strength of double weaves with the lighter feel of single weaves.
Are there specific regulations for gi colors in IBJJF competitions?
The International Brazilian Jiu-Jitsu Federation strictly regulates gi colors, allowing only white, royal blue, or black uniforms for official competition. These rules make sure a professional appearance and prevent visual distractions during matches. Every gi must be uniform in color, meaning the jacket and pants cannot be mismatched.
An important nuance involves the collar and stitching, which must also conform to the color requirements. While the primary fabric must be one of the three approved colors, minor details like contrast stitching or embroidery are permitted, provided they remain subtle and do not obscure the overall color profile. Competitors who arrive with non-compliant colors, such as red or camouflage, are typically disqualified or forced to borrow a tournament-provided gi before they are allowed to step onto the mat.
How does the shrinkage rate of a gi affect the initial selection process?
Most cotton gis shrink between 3% and 8% after the first few hot washes, so you should select a size that fits slightly loose when new. If you choose a perfectly fitted gi, it will likely become too small after a few cycles in the dryer.
| Fabric Treatment | Expected Shrinkage |
|---|---|
| Pre-shrunk cotton | 1-3% |
| Standard cotton | 5-8% |
| Hemp blends | 2-4% |
| Synthetic fabrics | 0-1% |
Use these percentages to calculate if a gi will remain within legal length requirements after your preferred laundry routine.
What is the recommended maintenance routine to prolong the lifespan of a gi?
You should wash your gi immediately after every training session using cold water and hang it to dry to prevent fabric degradation.
- Cold water prevents the fibers from breaking down prematurely and keeps the cotton from shrinking excessively during the wash cycle.
- Detergent amounts should be kept to a minimum to avoid chemical buildup that makes the fabric stiff and abrasive over time.
- Hang drying is the only way to avoid the intense heat of a dryer, which is the primary cause of collar warping.
- Vinegar rinses help neutralize odors and keep the fabric soft without relying on harsh fabric softeners that clog the weave.
Why is it important for a gi to be IBJJF legal for tournament participation?
Tournament participation requires an IBJJF-legal gi to make sure that all competitors adhere to the same standards regarding fabric thickness and fit. Officials use a specialized gauge to measure the sleeve length and the distance between the collar and the chest, ensuring no one has an unfair advantage. For example, if a sleeve is too short, an opponent cannot grip it effectively, which alters the technical nature of the match.
The nuance here is that even a legal gi can be rejected if it is deemed excessively dirty or torn. Referees have the authority to disqualify a competitor if the gi is in poor condition, as frayed edges or significant holes can pose a safety risk to fingers and toes during intense grappling. Always inspect your gear for structural integrity before heading to a tournament.
What essential gear should a new student acquire beyond the gi?
New students should prioritize acquiring a few key items that improve hygiene and safety while training on the mats.
- Mouthguards protect your teeth from accidental impacts or clenching during high-intensity sparring sessions, preventing expensive dental issues.
- Rashguards worn under the gi provide a layer of protection against mat burn and help manage sweat, keeping the gi from becoming overly saturated.
- Fingernails must be kept trimmed short at all times to prevent accidental scratches or injuries to training partners during grip fighting.
- Flip-flops are essential for walking between the locker room and the mat, as they prevent you from tracking bacteria onto the training surface.
Mistakes to avoid
- Assuming the belt is high quality. The included belt is meant for beginners and often loses its shape quickly; expect to upgrade within a few months.
- Ignoring the product description. Some specialized or high-end manufacturers do not include a belt, leading to a surprise when the package arrives.
- Washing the belt with the gi. Belts often shrink differently or bleed dye onto the gi, so wash them separately to maintain the appearance of both.
Preparing for your first class
Don't stress if your gi arrives without a belt, as most gyms keep a supply for new students. Focus your initial budget on finding a gi that fits your body type properly rather than worrying about the quality of the starter belt.
