How Should Colorfastness Requirements Be Defined for Dark Activewear?

Dark activewear needs defined resistance to relevant washing, rubbing, and perspiration exposures.

Material decisions affect the finished garment, so assessment should consider stretch, care, decoration, and the intended use. A swatch may be suitable for preliminary comparison, but relevant bulk-fabric checks and garment-level trials are still needed before the order is manufactured. Agree methods and acceptance limits with the testing provider.
