There are four main weave types that are used for BJJ (Brazilian jiu jitsu) gis. They are single weave, double weave, gold weave, and pearl weave.
- Single Weave: light and cost effective and pretty common in beginner gis
- Double Weave: heavy and durable and more common in Judo gis
- Gold Weave: less common, more expensive and little more comfortable but prone to shrinking
- Pearl Weave: most popular weave type in BJJ gis and are, generally, lightweight and pretty durable
Basically, different weaves are represented as different patterns in your gi. Some may be more durable and heavier, and some may be more comfortable.
Lastly, ripstop fabric is very light weight and most commonly used in BJJ and judo gi pants but is sometimes use in the jacket as well.
For beginner’s we recommend going with a light weight pearl weave or single weave gi.
Table Comparing Different Weave Types
| Weave Type | Description | Common Uses | Weight | Durability | Comfort Level | Special Characteristics |
|---|---|---|---|---|---|---|
| Single Weave | Lightest and thinnest, quick to dry, cost-effective, strong | Beginner gis | 1.6-1.8 kg | Strong | Moderate | Uniform pattern, sometimes called ‘honeycomb’ |
| Double Weave | Heavy, tough, difficult for opponents to grip, restricts movement | More Common with Judo Gis | Heaviest | Very High | Low | Thick vertical threads, prominent horizontal ones |
| Gold Weave | Balance between single and double, durable, soft, prone to shrinkage, more expensive | Traditional BJJ | ~2 kg | High | High | Ladder-like pattern, softer feel |
| Pearl Weave | Most popular BJJ fabric, strong, durable, available in various styles from lightweight to premium | Most BJJ gis | Variable | Very High | High | Appearance of aligned ‘pearls’, most common |
What Is GSM?
GSM means Grams per Square Meter. GSM measures the weight of gi fabric. Gis with a higher GSM are typically more durable but heavier, while lower GSM gis are lighter.
The range of GSM in Brazilian jiu jitsu gis varies widely, typically between 375 and 890 GSM. Judo gis tend to be at the higher end of this range.
It should be noted that the IBJJF (International Brazilian jiu jitsu Federation) requires that all competitors gi’s weigh between 380 and 650 GSM.
In general, heavier gis may seem harder to grab, and lightweight gis feel more comfortable.
Understanding GSM in BJJ Gis Plus Examples
Again, GSM stands for Grams per Square Meter. It helps quantify the weight of the gi fabric, giving you a general idea of the material’s density and thickness.
The GSM of a BJJ gi influences several factors:
- Training: Higher GSM gi’s tend to be harder to grip
- Durability: Higher GSM fabrics tend to be more resilient against wear and tear.
- Comfort: A higher GSM can mean a rougher texture, while a lower GSM may feel lighter and softer.
Here’s a basic GSM classification:
- Lightweight Gi: Less than 450 GSM
- Middleweight Gi: 450-550 GSM
- Heavyweight Gi: More than 550 GSM
Examples of Gis of Different Weave’s and GSM
| Brand | Typical GSM Range | Weave Type |
|---|---|---|
| Gold BJJ Aerowave Gi | 275 GSM | Pearl Weave |
| FUJI Suparaito | 350 GSM | Pearl Weave |
| Hayabusa Lightweight Gi | 420 GSM | Pearl Weave |
| FUJI All-Around GI | 550 GSM | Single Weave |
| Tatami | 550 GSM | Pearl Weave |
How to Choose the Right Weave Type for You
Some Gi Factors to Consider
Weight and Flexibility
Weight of the gi often corresponds with the weave density, typically measured in grams per square meter (GSM). A single weave gi is usually lighter and offers more flexibility, making it suitable for beginners or those who desire ease of movement. In contrast, a double weave provides a heavier and more rigid option, favored for its durability for judo gis. .
Flexibility adds to the comfort and range of motion, which is crucial during grappling. A pearl weave is known for its balance between lightness and toughness, hence offering a good level of flexibility without sacrificing strength.
Climate and Training Intensity
Climate can greatly impact the practitioner’s comfort and performance. In warmer environments, a lighter weave like single or pearl weave is preferred due to better breathability, helping to reduce overheating.
Training Intensity dictates the durability required from the gi. High-intensity sessions and frequent training demand a more resilient fabric, such as double weave or gold weave, to withstand the rigorous activity without excessive wear and tear.
Frequently Asked Questions
What are the different types of weaves in BJJ and what do they mean?
There are four main weave types that are used for BJJ (Brazilian jiu jitsu) gis. They are single weave, double weave, gold weave, and pearl weave. Single weave is more affordable and light weight, double weave is heavier and used more for judo gis. Gold weave is used more in traditional gis and is prone to shrinking. Pearl weave is the most common weave type used in modern gis and is a good balance of comfort and durability.
What distinguishes single weave and double weave gis in terms of durability and comfort?
Single weave gis are lighter and more comfortable, suitable for beginners or hot climates, whereas double weave gis are heavier and more durable, favored for their resistance to wear during intensive training.
Can you use the same gi for both BJJ and judo, or are there specific requirements?
BJJ and Judo gis have distinct cut and fabric specifications; Judo gis typically have wider sleeves and are more robust, while a BJJ gi is more fitted, with a shorter jacket and sleeves. Cross-usage is not recommended due to these differences and the respective sport’s regulations.
Which gi weave offers the highest resilience for intense grappling sessions?
The double weave is the most resilient for grappling, offering increased fabric density and weight, which contributes to its durability in intense training and competition.
How does the gold weave differ from pearl weave in BJJ gis, and which is preferred by practitioners?
Gold weave gis balance durability and comfort and are usually thicker and slightly more comfortable than pearl weave. Pearl weave gis, on the other hand, are known for their lightness, strength, and quick drying properties, making them a popular choice among practitioners.
