A superior rash guard requires high-performance fabric and the most stable ratio of material composition. Nylon (polyamide) makes the rash guard quick-drying, low moisture absorption, and reduces resistance. Nylon has excellent strength and excellent drape. It is abrasion-resistant and also significantly prevents shrinkage. Spandex (elastane) is more durable than rubber, soft, lightweight, and has excellent elasticity, providing compression and not breaking or deforming. Management Number: 18
