The Ronin Heavyweight Karate gi is made of 100% cotton  14oz. Duck Canvas, as most good heavyweight gis are. It is cut in the traditional style, but is actually cut a bit large because it will shrink anywhere from 1 to 3 inches when it is first washed and dried. The pants are the traditional drawstring pants.

Stiff enough that they make a rewarding snapping sound when Kata forms is executed.
