The 2XU Women's Aero Long Sleeve Top combines a moisture-wicking front and lightweight, breathable mesh back panel to keep you cool, dry and comfortable during your run. The back panel enhances breathability and ventilation while the main panel features an inner layer to wick sweat away from your skin and an outer layer to disperse moisture on the surface. Reflective logos and trims provide 360-degree visibility in low-light conditions.
