Re: Need a new Dogi
6 or 7 years seems to be a reasonable lifespan for most judo-gis. I find that after about 6 years, they are still wearable, but they start to fray a bit.
Anyway, I just bought a "Miyabi" keiko-gi from Iwata, and I love it. It's really soft, and it's a lot lighter than most other gis I have owned. I have no idea about how durable it is though.
