Top Tips for Choosing the Right BJJ Gi Size

Brazilian Jiu-Jitsu (BJJ) is a martial art that has gained immense popularity worldwide due to its effectiveness, practicality, and the emphasis it places on technique over brute strength. One essential piece of gear for any BJJ practitioner is the gi, also known as the kimono. Choosing the right BJJ gi size is crucial not only for comfort and performance but also for compliance with competition regulations. In this comprehensive guide, we will explore everything you need to know to choose the perfect gi size, including factors such as body type, brand variations, and personal preferences. We will also touch upon the importance of long sleeve rash guards and short sleeve rash guards in your BJJ training.

Understanding the Basics of BJJ Gi

Before diving into the specifics of choosing the right gi size, it’s important to understand the basic components and purpose of a BJJ gi. A gi consists of three main parts:

1. Jacket (Kimono Top): This is the upper part of the gi, featuring a thick, durable fabric that can withstand the rigorous demands of BJJ training and competition.
2. Pants: The lower part of the gi, made from reinforced material to resist tearing and provide mobility.
3. Belt: The belt is used to tie the jacket closed and indicates the practitioner’s rank.

The gi is not just a uniform; it’s a tool that can be used to perform various techniques and submissions. Therefore, its fit and comfort are paramount.

Importance of Choosing the Right Gi Size

Choosing the right bjj gi size is important for several reasons:

• Comfort: A gi that is too tight or too loose can be uncomfortable and hinder your movement, making it difficult to train effectively.
• Performance: A properly fitted gi allows for better mobility, which is crucial for executing techniques.
• Safety: An ill-fitting gi can increase the risk of injuries, both to yourself and your training partners.
• Competition Compliance: Different organizations have specific requirements for gi sizes, and an improperly sized gi can lead to disqualification.

Factors to Consider When Choosing a BJJ Gi Size

1. Body Type and Size

Your body type and size are the most important factors in determining the right gi size. BJJ gis come in various sizes that are usually denoted by a combination of letters and numbers (e.g., A1, A2, A3, etc.). The “A” stands for “Adult,” and the number indicates the size.

• Height: Most gi size charts take height into consideration. For example, someone who is 5’8” might fit into an A2 gi.
• Weight: Weight is another crucial factor. A heavier person might need a larger size to accommodate their build.
• Body Composition: Your muscle mass and body fat percentage can also affect the fit of the gi. A muscular person might need a larger size, even if they are not particularly tall.

2. Brand Variations

Different brands have slightly different sizing charts and cuts. Some brands cater more to leaner builds, while others offer options for stockier body types. Popular BJJ gi brands include:

• Atama: Known for their durability and traditional fit.
• Shoyoroll: Offers a tailored fit, often favored by competitors.
• Tatami: Known for their wide range of sizes and cuts.

3. Pre-Shrunk vs. Shrink-to-Fit

Some gis are pre-shrunk, meaning they have been treated to minimize further shrinking after washing. Others are shrink-to-fit, which means they will shrink after the first few washes. It’s important to follow the manufacturer’s washing instructions to achieve the best fit.

4. Personal Preferences

Personal preferences also play a role in choosing the right gi size. Some practitioners prefer a snug fit, while others like a bit more room for movement. Additionally, competition rules might dictate certain size requirements that you need to adhere to.

How to Measure for a BJJ Gi

Accurately measuring yourself is crucial for finding the right gi size. Here’s how you can do it:

1. Height: Stand straight against a wall and measure from the floor to the top of your head.
2. Weight: Use a scale to determine your current weight.
3. Chest: Measure around the fullest part of your chest, keeping the tape measure horizontal.
4. Waist: Measure around your natural waistline, typically just above the hips.
5. Arm Length: Measure from your shoulder to your wrist.

Using Size Charts

Once you have your measurements, refer to the size charts provided by gi manufacturers. Most brands offer detailed size charts on their websites. Here’s a general guideline for adult gi sizes:

• A0: Height 5’0” - 5’4”, Weight 95 - 120 lbs
• A1: Height 5’4” - 5’8”, Weight 125 - 155 lbs
• A2: Height 5’8” - 6’0”, Weight 155 - 190 lbs
• A3: Height 6’0” - 6’3”, Weight 190 - 225 lbs
• A4: Height 6’2” - 6’4”, Weight 225 - 250 lbs

Remember, these are general guidelines and can vary between brands.

Trying On Your Gi

When you receive your gi, try it on to ensure it fits correctly. Here are some tips for checking the fit:

• Jacket Fit: The sleeves should reach your wrists, and the jacket should cover your hips without being too tight or too loose.
• Pant Fit: The pants should be long enough to reach your ankles but not drag on the floor. They should also fit comfortably around your waist.
• Movement: Move around in the gi, performing some basic movements and stretches to ensure it doesn’t restrict your motion.

Long Sleeve Rash Guards and Short Sleeve Rash Guards

Rash guards are an essential part of a BJJ practitioner’s wardrobe. They are worn underneath the gi to provide additional comfort, prevent mat burns, and wick away sweat. There are two main types of rash guards: long sleeve rash guards and short sleeve rash guards.

Benefits of Long Sleeve Rash Guards

• Full Coverage: Long sleeve rash guards offer full arm coverage, protecting you from mat burns and skin infections.
• Warmth: They provide additional warmth, which can be beneficial in colder training environments.
• Sun Protection: If you train outdoors or participate in open-air competitions, long sleeve rash guards offer better protection against UV rays.

Benefits of Short Sleeve Rash Guards

• Cooling: Short sleeve rash guards allow for better ventilation and can keep you cooler during intense training sessions.
• Flexibility: They offer greater freedom of movement for your arms, which can be advantageous for certain techniques.
• Layering: Short sleeve rash guards are less bulky under a gi, making them more comfortable for some practitioners.

Choosing the Right Rash Guard

When choosing between long sleeve and short sleeve rash guards, consider the following factors:

• Training Environment: If you train in a hot climate or a well-heated gym, a short sleeve rash guard might be more comfortable. Conversely, if you train in a colder environment, a long sleeve rash guard can provide extra warmth.
• Personal Preference: Some practitioners prefer the feel of long sleeve rash guards, while others find short sleeves less restrictive.
• Purpose: If you compete frequently, consider having both types of rash guards in your wardrobe to adapt to different competition and training conditions.

Maintaining Your BJJ Gi and Rash Guards

Proper care and maintenance of your gi and rash guards will ensure they last longer and stay in good condition. Here are some tips:

Washing Your Gi

• Pre-Wash: Before washing, turn the gi inside out to protect the outer fabric.
• Temperature: Wash your gi in cold water to prevent shrinking and color fading.
• Detergent: Use a mild detergent that doesn’t contain bleach or harsh chemicals.
• Drying: Air dry your gi by hanging it up. Avoid using a dryer, as the heat can cause shrinkage.

Washing Your Rash Guards

• Temperature: Wash rash guards in cold water to maintain their elasticity and color.
• Detergent: Use a gentle detergent that’s free from bleach.
• Drying: Air dry rash guards or use a low-heat setting on your dryer.

Stain Removal

For tough stains, pre-treat the affected area with a gentle stain remover before washing. Avoid using bleach, as it can weaken the fabric and cause discoloration.

Conclusion

Choosing the right BJJ gi size is essential for your comfort, performance, and safety on the mats. By considering factors such as your body type, brand variations, and personal preferences, you can find a gi that fits perfectly. Additionally, incorporating long sleeve rash guards and short sleeve rash guards into your training attire can enhance your comfort and protect your skin. By following the tips and guidelines in this article, you’ll be well-equipped to select the perfect gi and maintain it for years of training and competition.
