A Gi (referred to in Brazil as a Kimono) is the uniform that is typically worn when training Jiu-Jitsu. It consists of 3 pieces: a jacket (or top), pants and a belt. The material in which the three pieces are made is specially reinforced to withstand the rigors of daily practice. Many Jiu-Jitsu players regard their Gi in the same way a knight would their armor. Most practitioners of Jiu-Jitsu who advocate the usage of the Gi cite the more technical aspect of grappling with a Gi. You will wear a Gi because it serves as a teaching tool for developing a strong grip, balance, and control. Fighting with the Gi requires a high level of precision and attention to detail- two tools essential for good Jiu-Jitsu. In addition, the Gi creates a lot of friction in between you, your opponent and the ground, helping your stamina and overall conditioning.
