My cotton indigo dyed hakamas have all been from Iwata since 1996 and in 'general' they have been excellent. However, I have found that the last one I ordered in 2007 isn't quite as good in terms of "quality" as my previous ones...
A very good hakama that I use for iaido is from Tozando, their Deluxe Polyester Aikido Hakama....

It has a nice feel and look. The pleats are sewn in. It washes easy and dries very quickly...and the quality is very good.
