The North Face Sleeveless Flight Hypervent Crew Tank Top Running Mesh Material Reflectors Size M Color: Black Size: Body width approx. 48cm Length approx. 66cm The inner tag has been cut off because it bothered me when wearing it. Only worn once, so it's in beautiful condition! Highly breathable mesh structure with water-repellent material on the skin side to reduce chilling from sweat. This is a high-performance running wear with a two-layer, bag-knitted structure for high breathability, designed for use in daytime races in spring and summer. Different mesh fabrics are mapped based on physiology. By streamlining ventilation inside the garment, overheating is reduced. Polyester water-repellent yarn is used on the skin side, considering the separation from the skin when sweating. The bag-knitted structure disperses moisture to the surface and prevents sweat from returning. Polygiene processing is applied for antibacterial and deodorizing effects with silver ions. Reflective logos are used to consider nighttime visibility.
