Buying Guide

Prioritize preshrunk fabrics

Preshrunk cotton or cotton-blend gis reduce post-wash shrinkage so the intended size remains reliable as kids grow

Choose lightweight weaves for faster drying

Ultra-light weaves weigh less and dry quicker, which helps maintain fit and comfort during frequent training and laundering

Check IBJJF compliance if competing

If your child will compete, look for IBJJF-approved cuts and labeling to ensure the gi meets tournament length and fit rules

Select brands with consistent size charts

Brands that publish detailed youth sizing and repeatable measurements make it easier to choose a growth-friendly size that lasts through multiple seasons

Balance room for growth with proper fit

Aim for a slightly roomy fit in sleeves and pants to accommodate growth without causing excess fabric that interferes with technique
