  • Otherwise, there is nothing wrong with simply hanging your jacket and pants out of the machine on the line.

  • The other main function is the increase in mobility, because with the karate suit significantly more athletic movements are possible than with a pair of jeans.
  • A secondary function of a particularly strong Gi is the“whip crack” at the end of a technique. This refers to the sound that occurs when you perform your movements at a very high speed and stop abruptly at the end point. Especially for masters, this effect enhances the technique through acoustic feedback.

Where does the karate suit come from?

The Gi, or Karategi, most likely originates from Judo and found its way into Karate probably through the contact between Judo founder Kanō Jigorō and Funakoshi Gichin. This detail is not proven, but the similarity speaks for it.
