Children's No-Gi BJJ Size Guide

Understanding competition rules ensures your uniform meets standards and prevents disqualification.

ADCC is the premier no-gi competition organization, setting the standard for elite competition. Rashguards and shorts must be tight-fitting to prevent grabbing and ensure fair competition. No pockets, zippers, or loose material are allowed that could provide advantages or cause safety issues. Shorts must provide adequate coverage while maintaining a tight fit. Always check specific ADCC event rules for current requirements, as standards may evolve.

Local no-gi tournaments may have relaxed rules compared to major organizations. Some allow looser-fitting shorts or have different coverage requirements. When in doubt, follow IBJJF standards to ensure compliance. Always check with tournament organizers for specific requirements before competing to avoid disqualification.

Proper care extends your uniform's life and maintains hygiene.

Start by checking all pockets and removing any items. Turn your gi or no-gi gear inside out to protect the outer fabric during washing. Use cold water (30°C or below) to prevent shrinkage, and select a mild detergent without bleach or fabric softener. Use the gentle or delicate cycle on your washing machine. For hand washing, use cold water with gentle agitation. On your first wash, consider pre-shrinking by washing in warm water if you want to minimize future shrinkage, though this is optional.

Air drying is the preferred method for preserving your uniform's quality and preventing shrinkage. Hang your gi on a hanger or lay it flat to dry. Avoid direct sunlight to prevent color fading. If you must use a dryer, use low heat only and remove the uniform promptly when dry to prevent wrinkles. Hang by the shoulders, not the collar, to maintain the gi's shape and prevent stretching.

Always wash your uniform after every training session for hygiene. Use cold water and turn items inside out before washing. Air dry when possible, check care labels, and wash separately, especially new gis. Never use bleach or fabric softener, as these can damage the fabric. Don't dry clean, iron (especially patches), leave wet gear in a bag, or use high heat. These practices will extend your uniform's life and maintain its quality.

Most cotton gis shrink 3-5% after the first wash, which is why many practitioners buy slightly larger. Pre-shrink new gis with a warm wash before first use if you want to minimize future shrinkage. Always account for shrinkage when purchasing - consider buying slightly larger if you're between sizes. Cold water washing minimizes shrinkage. If your gi shrinks too much, some brands offer exchange programs, but prevention through proper sizing is key.

For blood stains, rinse immediately with cold water, then apply hydrogen peroxide before washing. Sweat stains can be pre-treated with a white vinegar solution before normal washing. Mat marks require pre-treatment with stain remover and gentle scrubbing before washing. For general stains, treat immediately with cold water and avoid harsh chemicals. Always test stain removal methods on a small, inconspicuous area first.

Wash your uniform after every training session for hygiene and to prevent odors. Deep clean monthly with a vinegar solution to remove persistent odors and bacteria. Before competition, ensure your gi is freshly washed and pressed for a professional appearance. Never train in an unwashed uniform - it's unhygienic, disrespectful to training partners, and can lead to skin infections.

Understanding no-gi materials helps you choose gear that enhances your training.

Polyester is the primary material used for rashguards, offering excellent moisture-wicking properties and durability. It maintains its shape well and dries quickly, making it ideal for performance wear. However, polyester can retain odors more than natural fibers and is less breathable. It's the standard choice for rashguards and performance-focused no-gi gear.

Spandex and Lycra provide excellent stretch and compression benefits, making them essential for spats and compression shorts. These materials offer flexibility and form-fitting properties that enhance performance. However, they can lose elasticity over time and require careful washing to maintain their properties. Best for spats, compression shorts, and any form-fitting gear where compression and flexibility are priorities.

Nylon is a very durable material commonly used for no-gi shorts. It offers quick-drying properties and exceptional strength, making it ideal for high-intensity training. Nylon is lightweight yet strong, though it can be less breathable and flexible than other materials. Best for no-gi shorts where durability and quick-dry properties are priorities.

Polyester/spandex blends combine the best of both materials, offering moisture-wicking properties with stretch and compression. These blends provide optimal performance for rashguards and compression gear, creating comfortable fits that enhance training. While blends can be more expensive and require proper care, they offer superior performance characteristics. Best for performance rashguards and compression gear where both moisture-wicking and flexibility are important.
