Well i bought my first hakama and proper hard gi from Hombu itself. It was kind of a reward to getting my black belt
. All part of the experience. If you can get your hands on the Iwata brand if u ever do visit Japan, by all means do so. I think you can order it too. Mine is the synthetic kind and it holds up great and i seldom wash it and it's still in great condition. Don't know if it's polyester but the pleats hold after industrial washing, the colour is still there and it's just a marvel to use.
Check out their solid gis too! I roll on concrete with it and it works like a charm. Just thought it would be nice to voice an alternative.
