Ok, this is totally a new thing to me. I finally got my gi today. I've worn them in the past. Gi is required for this class. This is my first judo style gi. It's really heavy. All the others I've worn where not for grappling. Anyway my instructor told me today that I was not to wash my belt. He said it was tradition. ? What? Um I sweat like a waterfall! I'm sure my belt is going to get funky fast!! Anyway do you wash your belt?
