How to Measure
Wrap a measuring tape around your natural waistline — the narrowest part of your torso, usually just above the belly button. Keep the tape snug but not tight, and measure over a thin layer for the most accurate result.
Fit Notes
- • Mid-rise athletic taper — cut close, not compressing.
- • 9% Elastane gives generous 360° stretch.
- • Between sizes? Size up for a more relaxed fit.
- • Low-pro waistband sits flat under pants.
