What is My Fit?

Diamond Theory has 2 Fits for shirts:

Muscle and Mass

  • Muscle: This fit is designed with Bodybuilders in mind as this has an aggressive taper, bringing it right in at the waist.
  • Mass: This fit is designed with Strongmen in mind as this has a less aggressive taper as Strength Athletes tend to have a thicker core.

Please take this as a reference and refer to the size guide with your measurements.
