Why fabric weight and opacity should be reviewed together
Fabric weight alone does not confirm how a garment performs when stretched. Buyers should review weight, hand feel, recovery and opacity on the same approved sample, under the intended fit direction.
What the polyester-spandex blend contributes
On the verified 85/15 styles, polyester provides a smooth surface suited to sublimated graphics, while spandex provides the stretch required for a close performance fit.
Construction details worth specifying
- Sleeve length and raglan panel direction
- Seam placement and stretch compatibility
- Lower-hem grip requirement
- Logo, sponsor mark and panel-artwork positions
- Size range, fit direction, private labels and packaging
