Size guide


We understand how important the right fit is. The GymJam Size Guide offers comprehensive information on our sizing, so you can feel confident that you are buying the best size for you and your body type.

Please note: Sizes are true to fit and already tailored in a tapered fashion, please avoid ordering a smaller size than usual to compensate. We recommend you refer to individual products pages for more information.
