📏 Sizing Tip

Choose your true-to-waist size for the best fit. If you're between sizes, we recommend sizing up for a more relaxed fit or sizing down for a snugger fit. Our 4-Way Stretch fabric adapts to your body.

How to Measure

📐
Measurement Diagram
01

Waist Measurement

Measure around your natural waistline, where you normally wear your pants. Keep the tape measure snug but not tight.

02

Use a Flexible Tape

Use a flexible measuring tape for the most accurate measurement. If you don't have one, use a string and then measure it against a ruler.

03

Stand Naturally

Stand in a relaxed, natural position. Don't hold your breath or pull your stomach in.
