A Brazilian Jiu-Jitsu gi might appear simple at first, but the fabric’s weave shapes nearly every part of your training experience. The weave affects durability, airflow, weight, comfort, and even how much control an opponent can gain from gripping your jacket. Understanding the different weaves helps you choose a gi that actually matches your needs, whether you train daily or compete regularly.
TL;DR
- A lighter weave like single or low GSM pearl offers comfort and breathability but trades off some long term durability.
- A heavier weave such as double or high GSM fabrics delivers maximum toughness though it can feel warm and stiff.
- Pearl weave remains the most balanced choice while gold weave offers a classic feel and single or double weaves sit at opposite ends of weight and resilience.
Why Does the Weave You Get Matter?
The weave determines how tightly the threads interlock and how dense the jacket becomes. Because most of the gripping in BJJ happens on the gi itself, the weave influences how the jacket performs under stress. A lighter weave keeps you cooler but may wear down faster. A heavier weave withstands rough rolling, though it can feel warm and stiff. For anyone who trains consistently, selecting the right weave is more than a small detail because it dramatically affects comfort and longevity.
Single Weave
The single weave is the simplest and most breathable. It is light, soft from the beginning, and great for warm climates or long training sessions. It also tends to be affordable and quick to dry. The drawback is that its lighter structure may not handle years of heavy grip fighting. Still, for beginners or athletes looking for a competition friendly low weight jacket, the single weave remains a practical option.
Double Weave
A double weave jacket is rugged and built to handle the toughest sessions. The fabric uses more cotton, giving it a thicker and heavier feel. This makes the gi exceptionally durable and resistant to tearing or stretching. The downside is that it can feel warm and may require a break in period before it moves naturally. Many seasoned grapplers appreciate the durability and the almost armor like quality it provides during intense sessions.
Gold Weave
Gold weave once dominated as the perfect middle ground. It offered more resilience than single weave but stayed lighter and more flexible than double weave. Though it has become less common with the rise of pearl weave, many practitioners still enjoy its breathable pattern and comfortable drape. Gold weave jackets usually soften with time and tend to form around the body nicely without losing integrity.
Pearl Weave
Pearl weave has become the modern favorite because it balances strength, weight, and comfort better than most other styles. The small raised bumps along the fabric give structure without excessive heaviness. Pearl weave dries quickly, holds its shape, and remains crisp even after months of rolling. Its blend of durability and low weight makes it the go to choice for most competition legal lightweight gis.
What Is the Best Weave
There is no universally best weave because the ideal choice depends on climate, training intensity, and personal taste. If you need something cool and light, single weave or a lower GSM pearl weave works well. If you want the toughest jacket possible, double weave is the powerhouse. Gold weave delivers a traditional and comfortable feel, while pearl weave offers a modern balance that covers nearly all training styles.

What Is GSM and Why It Matters
GSM stands for grams per square meter and it measures how dense the fabric is. A higher GSM means a thicker and heavier jacket. A lower GSM keeps the gi lighter and cooler but may reduce longevity. Even two gis made with the same weave can feel completely different depending on their GSM. This makes GSM an important metric for determining how sturdy or airy a gi will feel over months of training.
Once you understand how each weave behaves, choosing a gi becomes much easier. The right weave can elevate comfort, help with weight management, and ensure your gear lasts through the demands of your training routine.
