Are Aikido or Judo uniforms made of rice?

Question

Is it really made of rice or something like that? I saw some are darker than others.

Do you know a good brand? if you know a link, that would be great.

Answer 1

No, most of them are made of cotton, some of silk and some of tetron (this synthetic material looks like silk but it needs less care).

Are you disappointed? :)

Probably the darker ones were made from cotton fabric which was not whitened. Natural color of cotton is close to ivory.
