Application
A good legging bends, squats and springs back — without going sheer under light. This page gathers the stretch knit structures that cover the yoga, running-tight and athleisure range.
A legging has to follow movement without restricting it, then return to shape. Elastane share and knit structure set both: stretch interlock moves in four directions with high recovery, while two-way elastane knits follow the body with less spring-back.
Squat-proof opacity is a matter of weight and tight construction: under stretch the loops open, and a thin, loose structure goes sheer. Fersan builds the chain under one roof — from its own filament to knitting, dyeing and heat-setting; each card carries the application rationale, the catalogue weight window and a technical data sheet.
180–300 g/m²
270–360 g/m²
210–320 g/m²
160–250 g/m²
130–220 g/m²
Weight windows come from catalogue data; final specs are confirmed on a sample.
| Weight window | 130–360 g/m² (3.8–10.6 oz/yd²) |
|---|---|
| Stretch / recovery | Four-way stretch interlock gives the highest spring-back; elastane share sets fit tracking |
| Opacity (squat-proof) | Resisting sheerness under stretch comes from weight plus tight construction; confirmed on a stretched sample |
| Moisture management | Fast-drying polyester filament plus optional hydrophilic (wicking) finish |

A squat-proof legging typically sits in the 220–300 g/m² four-way stretch-interlock window; lighter structures can go sheer under stretch. The final value is confirmed on a stretched sample against pattern and elastane share.
Sheerness is a matter of weight, knit tightness and colour: as the fabric stretches the loops open and a thin, loose structure lets light through. Higher-weight tight interlock and dark, saturated colours raise opacity; the target is tested with the legging under stretch.
For everyday, warmer joggers and hoodies, stretch French terry gives a structured hand; where athletic performance and high stretch lead, four-way stretch interlock is preferred. The two complement each other in one collection.
