How to measure

To choose the right size, follow the steps below:

Use a measuring tape for maximum accuracy (flexible tape, if possible).

Measure your chest

Wrap the measuring tape around the fullest part of your chest, just under the arms and across the shoulder blades. Keep it horizontal and snug, but not tight.

Measure your waist

Find the narrowest part of your torso, just above the belly button. Wrap the tape around your waist comfortably, leaving space for one finger.

Compare your chest and waist measurements to those on our size chart, and select the size that most closely matches your measurements for the best fit.
