Will you run a new personal record in the Matrix singlet? The Dynacool fabric of which the tanktop is made, causes the top to feel very comfortable during running. The fabric has a soft touch, that feels nice on the skin. The tanktop is also breathable and lightweight, causing you to stay cool while running. On the sides of the tanktop, you find reflecting accents. Because of this, the top is perfect for running in the dark too. You complete the look by combining the Matrix top with the Matrix short. And is it still a bit cold outside? Make sure you stay warm by combining the tanktop with the matching Matrix vest.
