The Fumetsu rash guard range is built for BJJ no-gi, MMA conditioning and grappling. The fit is a bodycon compression cut — close to the skin to minimise grip points for your training partner. Use the chart below to match your chest, waist and height to the right size.
Fit tip: Fumetsu rash guards run true to size. Order your usual training top size for a competition fit; size up if you prefer a slightly more relaxed feel for everyday training.

How to measure
- Chest: Around the fullest part of your chest, arms relaxed.
- Waist: Around your natural waistline at navel height.
- Height: Floor to crown in bare feet.
