The jiu jitsu gi is the uniform worn by people who practice Brazilian jiu jitsu during training. The word “gi” comes from the Japanese for “clothes.”

What Does The Jiu Jitsu Gi Look Like?

The jiu jitsu gi looks similar to other types of martial arts uniforms. Manufacturers construct it from thick, durable heavy cotton with reinforced drawstrings. Around the waist is a separate belt whose colors indicate the rank of the martial artist wearing them. Gi trousers are similarly reinforced and fasten around the hips with the aid of a drawstring.

Is The Jiu Jitsu Gi The Same As The Karate Gi?


The jiu jitsu gi and karate uniform, called the Karategi, is similar to the Brazilian jiu jitsu gi, but not identical. Karategis are made of thin, breathable cloth and their sleeves finish at the forearm, not the wrist. Brazilian jiu jitsu gis have thicker material and longer arms.

The difference in attire reflects differences between the two martial arts. Karate involves less pushing and pulling and involves more sweeping motions. Clothing, therefore, must facilitate large movements. Jiu jitsu, on the other hand, involves more grappling and tugging. Clothing, therefore, needs to be sufficiently strong to withstand training forces.
