I have an account with Tiger Claw which is located in Fremont, California. For our youth, I typically order the light weight/beginners karate uniform. They run anywhere from $10-$15 and have held up well.
For the teens/adults, they have the option of a medium weight karate gi or a single weave judo gi. The medium weight karate gi's have also held up very well and run anywhere from $15 - $25. It's not uncommon for us to have consectutive 100+ degree temperatures, at 7:00 PM, and these uniforms have been great.
The single weave judo gi's, depending on bleached or unbleached, run $35 - $45 and have held up well.

Hope that helps ...
