Which Fabric Color Tests Matter for Sweaty Workouts?

Sweaty-workout fabrics may need perspiration, rubbing, and washing colorfastness evaluation.

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. Assess staining as well as shade change.
