A guide to measuring

As a general rule, keep the measuring tape firm, but not too tight. If you're measuring yourself, try to take them more than once, to average out any change in your posture.

Measuring your chest:

Simply measure around the fullest part of your chest, keeping the tape level under your arms and across your back.

Measuring your waist:

Just measure around the narrowest part of your body at your hips.

Measuring for gloves:

Wrap a tape measure around your strongest hand just below the knuckles and fingers, make a loose fist. Please round up to the nearest size and (not down).
