Pros and Cons of Heavy vs Light Judogi
There are different opinions on a thick heavy weight Double Weave competition Judogi compare to a light weight Double Weave competition Judogi. For example the Mizuno Shiai vs the Mizuno Yusho Japan, Yusho Comp IJF certified Judogi. The Shiai is a stiffer and heavier gi (While not as heavy compares to older models like the Ichiban or Eurocomp or Adidas J930. The Yusho Japan is a light weight gi, some people have mistaken the Yusho Japan for a single weave. (I will explain the differences between a Single and a Double in Art of the Judo Gi).
The thinking goes, “If you can’t grip, you can’t throw”. While that maybe true but it is totally against the spirit of Judo. But I digress. The trouble with a heavier gi is that the person wearing it is not going to be able to move around as well as someone wearing a lighter weight gi. The Japanese team always wear light weight competition gi. There doesn’t seems to be a lack of medals from the Japanese team either.
From my personal experiences, I do tend to have better result when wearing a lighter weight gi. That little extra speed in movement seems to do the trick.
