Second layer made with two Thermo Fleece fabrics, both with a checked structure inside. The combination of different fabrics makes this the perfect second layer for any winter aerobic activity. Ideal for snowy winter conditions when you need warmth and breathability. The main fabric has a tighter structure inside, which makes it warmer; the fabric used on the side panels, under the arms and in the center of the back has a more open structure, which increases the breathability.
