Re: Opinions on Doyu gi's
I am not familiar with that brand myself.
I personally love Pirhana Gear gi. But the heavy weight karate gi that I prefer is really warm for a climate like yours. The hardly shrink at all and wear very well though. And the fabric is nice and does not take a lot of time to break in. I am not familiar with their aikido gi.
A few people in my dojo have used Nine Circles and seem to like them although the one girl said that the heavy weight gi is much too stiff for her taste.
