Size Guide
Finding the right fit is important whether you're training, competing, or wearing your gear every day.
Use the size charts below as a general guide. If you're between sizes, consider how you prefer your gear to fit:
-
For a tighter, competition-style fit: size down when appropriate.
-
For a more relaxed fit: size up.
-
For rashguards: chest measurement is the most accurate sizing method.
-
For gis: weight and height recommendations should be used together for the best fit.
