How to Measure for Performance Underwear:
Waist Size: Measure around the natural waistline, typically above your belly button.
Hip Size: Measure around the fullest part of your hips and buttocks.
Inseam: Measure from the crotch to the desired length (usually ankle or mid-thigh, depending on style).
Choosing the Right Size:
For Comfort: Ensure the waistband of the underwear sits comfortably around your waist without digging in, and that the material around the hips doesn’t feel too tight.
For Activity: Performance underwear is designed to stretch and support your body during physical activity, so don’t worry if it fits snugly — the fabric will move with you.
