A gi (着), meaning dress or clothes, is composed of a heavy cotton jacket, reinforced drawstring pants, and a belt which communicates rank.
It is common in tournaments to see competitors wearing ripstop pants with a standard cotton gi top.
Due to the nature of wrestling/grappling and the diseases that can come from close contact between people, the gi is typically washed after each class.
To preserve the life of the gi, bleaching is highly discouraged, as this can weaken the fibers of the material and cause them to tear more easily.
Line drying in bright sunlight is commonly suggested to help remove smells from the gi, due to the bacterial killing properties of UV light.
[5] While most gis sold today are made of a colorfast material, some manufacturers recommend that a darker coloured gi (blue, black, red, etc.)
Jiu jitsu regulations allow for tighter cuffs on the pants and jacket, and the skirt (section of the gi beneath the belt) is shorter.
This allows the practitioner to benefit from a closer fit, providing for more fluid movement and less material for an opponent to manipulate.
Team, sponsor, and manufacturer's patches are often more prominently displayed on a Jiu-Jitsu gi than would be allowed in judo.
