Our MeshBack O-top is made with FlexShield fabric on the front and full mesh fabric on the back, providing reliable coverage together with enhanced ventilation. Both materials are durable, breathable, and include antibacterial properties to help maintain freshness throughout the day. Their moisture-wicking capability supports temperature regulation, keeping you dry during steady or intense movement. With a soft, smooth feel against the skin, this top is designed for consistent comfort over long distances. A practical choice for both training sessions and races.
