A gi is the term for the Brazilian Jiu-Jitsu uniform worn during training and competitions. When selecting a gi, it is important to consider fitment, the IBJJF-approved sizing, and colors. A true-to-size gi ensures comfort and flexibility on the mats, improving athletic performance. The bottom of the gi top should reach your thighs, the sleeves should reach the waist, the bottom of the pants should rest just above the ankles, and the belt should not exceed a width of 5 cm. Oversized or loose gis can look unprofessional and hinder movement. Use the four-finger test to check whether the gi’s sleeves are the right length. Extend your arm, bend four fingers backward, and try to touch your wrist. If the sleeves do not reach your fingers, your gi will not be considered IBJJF-approved. While you may be allowed to train in academies, you won’t be able to compete at the highest levels. A good BJJ gi is crafted from high-quality cotton, preferably with a pearl weave. Super thick and tough gis make grappling difficult for the wearer, their training partners, and their opponents. Maintaining your gi is required since torn ones are not allowed at academies or IBJJF tournaments. BJJ gis are also available in a wide range of colors. While training, you can wear a gi of any color unless there is a strict color policy at your BJJ academy. However, if you want to compete in an IBJJF competition, you must wear a white, blue, or black Jiu-Jitsu gi depending on the division you will fight in. Before purchasing a BJJ gi, carefully read the criteria for selecting the perfect BJJ gi for the right occasion.
