7 Reasons Why Your BJJ Gi Might Be Shrinking

Brazilian Jiu-Jitsu (BJJ) is a dynamic martial art that requires practitioners to wear a gi, a traditional uniform consisting of a jacket, pants, and a belt. A well-fitted gi is essential for performance, comfort, and safety during training. However, many BJJ practitioners encounter the frustrating problem of their gi shrinking over time. Understanding the causes of gi shrinkage and how to prevent it can save you from frequent replacements and ensure your gi maintains its shape and functionality. In this article, we explore the seven primary reasons why your BJJ gi might be shrinking and provide practical tips to mitigate this issue.


1. Improper Washing Techniques


High Water Temperature


One of the most common reasons for gi shrinkage is washing it in hot water. High temperatures can cause the fabric, usually cotton, to contract. This is especially true for new gis that haven't been pre-shrunk. Washing your gi in hot water can lead to significant shrinkage after just one wash.


Harsh Detergents


Using harsh detergents can also contribute to gi shrinkage. Some detergents contain chemicals that can weaken the fibers of the fabric, causing them to shrink over time. It's advisable to use mild detergents specifically designed for delicate fabrics or sportswear to preserve the integrity of your gi.


Overwashing


Frequent washing can accelerate the wear and tear of your gi, leading to shrinkage. While it's important to keep your gi clean to maintain hygiene, overwashing can cause the fibers to break down faster, resulting in a shrunken and misshapen gi.


Washing Tips


To prevent shrinkage, wash your gi in cold water and use a gentle cycle. Avoid using bleach or fabric softeners, as these can damage the fibers. Instead, opt for detergents that are free of harsh chemicals. Washing your gi inside out can also help protect the fabric.


2. Improper Drying Methods


High Heat Drying


Just like hot water, high heat from dryers can cause your gi to shrink. The intense heat can cause the cotton fibers to contract, making your gi smaller and tighter with each drying cycle. This is a common issue for practitioners who use a dryer to speed up the drying process.


Direct Sunlight


Drying your gi in direct sunlight can also lead to shrinkage. The ultraviolet rays from the sun can weaken the fibers and cause them to shrink. Additionally, prolonged exposure to sunlight can cause the colors of your gi to fade.


Drying Tips


Air drying is the best method to prevent shrinkage. Hang your gi in a well-ventilated area, away from direct sunlight. If you need to use a dryer, opt for a low-heat setting or a tumble dry option. Removing your gi from the dryer while it's still slightly damp and then air drying it can also minimize shrinkage.


3. Fabric Quality and Weave Type


Low-Quality Fabric


The quality of the fabric used in your gi plays a significant role in its durability and resistance to shrinkage. Low-quality cotton or blends are more prone to shrinking. Investing in a high-quality gi made from premium cotton or a durable blend can help reduce the risk of shrinkage.


Weave Type


The weave type of your gi can also impact its tendency to shrink. Different weaves offer varying levels of durability and shrinkage resistance:



  • Single Weave: Lightweight and comfortable but more prone to shrinkage.

  • Double Weave: Heavier and more durable, with less shrinkage.

  • Gold Weave: A balance between single and double weave, offering moderate shrinkage resistance.

  • Pearl Weave: Popular for its durability and minimal shrinkage, making it a favored choice among practitioners.


Choosing the Right Gi


When selecting a gi, consider the weave type and fabric quality. Higher-quality gis might come with a higher price tag, but they offer better longevity and resistance to shrinkage, making them a worthwhile investment.


4. Improper Storage


Folding and Storing Wet


Storing your gi while it’s still damp can lead to shrinkage and mildew growth. The moisture can weaken the fabric fibers and cause them to contract. Always ensure your gi is completely dry before folding and storing it.


Compressed Storage


Storing your gi in a compressed space, such as a tightly packed bag or drawer, can cause it to lose its shape over time. The pressure can cause the fibers to compress and shrink.


Storage Tips


Store your gi in a cool, dry place with adequate ventilation. Use a hanger to keep it in shape, and avoid folding it tightly. If you need to store it in a bag, choose a breathable one that allows for air circulation.


5. Pre-Shrinking Issues


Lack of Pre-Shrinking


Some gis are not pre-shrunk during the manufacturing process, which means they are more likely to shrink significantly after the first few washes. Always check the product description to see if the gi is pre-shrunk.


Initial Washing


Even pre-shrunk gis can experience some shrinkage during the initial washes. It's essential to follow the care instructions provided by the manufacturer during this period to minimize shrinkage.


Pre-Shrinking Tips


If you're unsure whether your gi is pre-shrunk, take extra care during the first few washes. Use cold water, a gentle detergent, and air dry the gi to minimize the risk of shrinkage.


6. Incorrect Sizing


Buying the Wrong Size


Purchasing a gi that is too large with the expectation that it will shrink to the perfect fit is a common mistake. This approach can lead to an ill-fitting gi if it doesn’t shrink as expected or shrinks too much.


Sizing Charts


Gi sizing can vary between brands, so relying solely on your usual clothing size might not be accurate. Always refer to the sizing charts provided by the manufacturer and consider their recommendations for shrinkage.


Tailoring


If you find that your gi is slightly too large, consider getting it professionally tailored rather than relying on shrinkage. This ensures a perfect fit without the risk of over-shrinkage.


Sizing Tips


Take accurate measurements of your body and compare them with the manufacturer’s sizing chart. If in doubt, consult with fellow practitioners or instructors for brand recommendations and sizing advice.


7. Fabric Stretch and Wear


Natural Fiber Stretching


Over time, the natural fibers in your gi can stretch with regular use. This can give the illusion that your gi has shrunk when, in fact, it’s the fibers returning to their natural state after being stretched during training.


Wear and Tear


Regular training puts a lot of stress on your gi, causing the fibers to wear down and contract over time. This natural wear and tear can lead to gradual shrinkage.


Maintenance Tips


To minimize the impact of wear and tear, rotate between multiple gis if possible. This gives each gi time to rest and recover between training sessions. Regularly inspect your gi for signs of damage and address them promptly to prolong its lifespan.


Conclusion


Understanding the reasons behind gi shrinkage can help you take better care of your bjj gi, ensuring longevity and maintaining a proper fit. By following proper washing and drying techniques, selecting high-quality fabrics, storing your gi correctly, and paying attention to sizing and pre-shrinking, you can minimize the risk of shrinkage. Investing time and effort into gi maintenance not only preserves your investment but also enhances your training experience.


Whether you prefer long sleeve rash guards or short sleeve rash guards under your gi, maintaining your gear in top condition is crucial. Proper care and attention to detail can make a significant difference in the lifespan and performance of your BJJ gi, allowing you to focus on what truly matters – your training and progress in Brazilian Jiu-Jitsu.
