HOW TO MEASURE

Grab a tape measure, write down the measurements and compare with our size chart for the right size. For best results, take measurements over your underwear. If your measurements fall between sizes, we suggest that you size up for a better fit.

1. Hips

Holding the tape horizontally measure around the largest part of your hips keeping the feet close together.

2. Inseam

Using pants that fit well, measure the crotch seam to the ankle bone
