BJJ Gi | Brazilian Jiu Jitsu Gi | Mens Womens Kids

BJJ gi sizing varies by brand but is generally based on height and weight. Most brands use a letter and number system (e.g. A1, A2, A3 for adults, M0–M4 for kids). As a general guide, measure your height and weight and cross-reference with the size guide on each product listing. If you are between sizes, size up as gi fabric can shrink slightly after washing. Contact us if you need help choosing the right size.

For most practitioners, a middleweight gi (350–550gsm) is the best all-round choice for year-round training. It is durable enough for regular rolling, comfortable in most gym temperatures and suitable for both training and competition. A lightweight gi is better for competition or training in warm environments. A heavyweight gi offers more durability and is harder for opponents to grip, but can be uncomfortable in warm gyms.

For IBJJF-sanctioned competitions, white, blue and black gis are the accepted colours. The gi must be a single solid colour with no large patches or non-standard designs. Other governing bodies may have different rules — always check the specific competition rules before purchasing a gi for competition use. For club training, most gyms accept white, blue, black, navy and grey gis.

To care for your BJJ gi, wash it after every training session to prevent bacteria and odour build-up. Use a cold or warm wash (30–40°C) to prevent shrinkage and preserve the fabric. Avoid tumble drying where possible — air dry flat or on a hanger to maintain the shape and prevent shrinkage. Do not use bleach or fabric softener. Check the care label on your specific gi for manufacturer recommendations.
