You evidently just acquired your first new judogi. J  Hopefully, everything you ever want or need to know about your new gi, you will be able to read here.  Read closely and you will learn a bit more than that.

The judogi is the traditional and official uniform that we use to practice judo.  Other forms of martial arts use the same or similar uniform, some with additional parts, and sometimes have different names for their gi.  It is sometimes called a dogi (uniform for practicing the way), or keiko-gi (practice uniform).  Often, we simply describe it as our “gi”.
