For leggings and tights the working specification is a four-way stretch knit with 10-20% elastane: cotton-elastane jersey for everyday wear, polyamide-elastane for performance, and interlock or scuba for opaque winter styles. Below about 10% elastane the garment bags at the knees, which is the number one complaint in the category.
How do the fabric options compare?
| Fabric | Weight | Elastane | Best for |
|---|---|---|---|
| Cotton-elastane jersey | 200-260 g/m² | 8-12% | Everyday, casual leggings |
| Polyamide-elastane | 190-280 g/m² | 15-25% | Sport, compression, yoga |
| Interlock with elastane | 220-280 g/m² | 8-10% | Opaque, children's styles |
| Scuba stretch | 250-350 g/m² | 5-10% | Structured winter leggings |
| Brushed / thermal knit | 280-380 g/m² | 8-12% | Winter thermal leggings |
How do you specify opacity?
Squat-test opacity depends on fabric weight and knit density together, not on colour. As a working rule, below 220 g/m² a stretched knit becomes translucent in light shades. If the range includes light colours, either move to 240 g/m²+ or use an interlock construction, which is double-faced and inherently more opaque.
Why does recovery matter most to customers?
Elongation figures sell fabric; recovery figures keep customers. Test it the way the garment fails: stretch a sample 50% at the knee position, hold it for 30 seconds, release, and measure how much of the original dimension comes back. Anything under about 95% recovery will show knee bagging within a season.
Which comfort details reduce returns?
- Flatlock or coverstitch seams — a standard overlock seam chafes under compression.
- A wide, self-fabric waistband distributes pressure instead of rolling.
- A gusset panel removes the four-way seam intersection at the crotch, which is the most common failure point.
How do care and lifespan work?
Elastane is destroyed by heat, chlorine and fabric softener — not by wear. Wash at 30 °C, no softener, no tumble dryer. Printing this on the care label measurably reduces "lost its shape" returns.
