The performance running shirt is functional for high-intensity training and light enough for the rigors of a race. It offers extreme comfort and softness and is one of those shirts you barely feel when you wear it. The microfiber fabric prevents chafing, irritation or sports odors. Finely interlaced ventilation lines on the front and back and along the sleeve ensure optimum breathability. Perspiration and moisture are quickly wicked away, so a pleasant feeling remains even during intensive workouts. The loose yet slim fit combined with a seamless design offers incredible freedom of movement, allowing you to remain relaxed and efficient as intensity increases. The shirt's efficiency is complemented by a fast-paced striped design for a trendy look .
