Leggings pass squat tests not because they are “thick,”
but because they are engineered for stretch under load.
From a factory perspective, squat-proof performance depends on:
If any one of these fails, the fabric turns sheer the moment the wearer squats.
Squat-proof is not a feature.
It is a system.
In production, a squat test simulates:
A legging passes when:
Most returns happen because this test is never performed at factory level.
From my production experience, failures come from:
These issues don’t show on a mannequin.

| Engineering Layer | What It Controls |
|---|---|
| Yarn Selection | Fiber separation under load |
| Knit Density | Loop opening during stretch |
| Pattern Tension | Stretch distribution |
| Seam Type | Stress whitening |
| Dye Method | Opacity at 150% stretch |
