A Gi (sometimes referred to as 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.
