Crafted from lightweight recycled polyester jersey fabric, this T-shirt is highly breathable so it keeps you comfortable in hot weather or when working up a sweat. The Deltapeak™ technology lets warmth escape from your body while letting cool air circulate. The fabric's quick-dry properties prevent sweat from building up as you rack up the kilometres. With advanced UV protection to keep the worst of the sun’s rays off you, the women's Sunset T-shirt is ideal for summer endurance sports.
