Jeans sizes are a close guide rather than an exact match — waist sizing varies between denim brands.
How to measure
Use a soft tape measure over bare skin or light clothing, and keep it level the whole way round: snug, but not pulled tight.
Measure around your natural waistline, where the waistband of your jeans normally sits. Stand relaxed and breathe out, without holding your stomach in.
How they should fit
- Waistband: comfortably secure around your waist, without digging in.
- Leg openings: gently hugging your thighs without digging in, so they stay in place as you move.
- Pouch: the 3D-contoured SculptPouch™ gives you room, while its elastic border gently keeps everything in place.
- Inner thighs: the smooth RunFree™ panels sit between your thighs to help reduce friction.
Between sizes
Choose the larger size, and do the same if you prefer a little more room. The fabric has natural stretch, so the bigger size gives a little more room through the waist and thigh without going loose.
Signs you need a different size
- Try a size up if the waistband digs in or leaves a deep mark, the leg openings pinch, or the pouch feels tight.
- Try a size down if the waistband slips or gaps, or the fabric bunches or sags.
