Practitioner Notes
Purple Belt
Marco V.
4x/week · San Diego, CA
The Core Gi feels simple in the right way. Light enough for daily rounds, but the jacket still has structure when people start pulling on the collar.
Practitioner fit note.
Brown Belt
Daniel R.
Open mat rounds · Weekly training
It is the gi I would keep in the rotation every week. Clean fit, good pant movement, and no extra details that make it feel loud.
Practitioner fit note.
Black Belt
Rafael M.
15+ years on the mat
It has the right balance for a daily gi. Not too heavy, not flimsy, and clean enough that I can wear it to teach or roll hard rounds.
Practitioner fit note.
