The Fumetsu Kids BJJ Gi range uses the M-system (M00 to M4) sized to height and weight for young grapplers. The cut is reinforced for school-night rolling and comp prep, with a slightly roomier sleeve and skirt so growing kids get more than one season out of it.
Fit tip: If your child is between two sizes, pick the larger one — the Gi will shrink slightly on its first hot wash, and the bigger size gives them room to grow.
How to measure
- Height: Stand the child against a wall in bare feet and measure floor to crown.
- Weight: Use current training weight.
