A gi is the traditional uniform worn in Brazilian Jiu-Jitsu, and it is closely related to the kimono.
The term “gi” comes from Japanese martial arts and refers to a durable training uniform made of a jacket, pants, and belt. While people sometimes use the word kimono casually, in Brazilian Jiu-Jitsu the correct term is gi. The design is similar in spirit but modified to be thicker and stronger to handle gripping and grappling.
Training in a gi allows students to use grips on the sleeves, collar, and pants, which adds an extra layer of technique and control to the art. Gi training helps develop strong fundamentals, patience, and precision, and it plays a major role in traditional Brazilian Jiu-Jitsu practice.
