The Fumetsu Youth rash guard range is sized for kids and juniors training BJJ, MMA and no-gi grappling. The compression cut hugs close to give partners less to grip, with extra reinforcement at the seams for school-night roll sessions. Use the chart below to match your child's height and chest to the right size.
Fit tip: If your child is between two sizes, pick the larger one — they'll get a bit more room to grow into it without losing the compression feel.

How to measure
- Chest: Around the fullest part of the chest, arms relaxed.
- Height: Floor to crown in bare feet.
