Football Base Layers: Essential Performance Layers. Base layers (also called skins or compression wear) are worn directly under your football kit to regulate body temperature, wick away sweat, and provide muscle support. They can help players maintain muscle temperature in colder weather. This temperature regulation, in turn can reduce the risk of injury and, according to some research, increase power and strength. Base layers keep players dry and comfortable in all weather - warm in winter, cool in summer. The light compression can help to reduce muscle fatigue and improve recovery, especially in the legs. FORZA Base Layers deliver excellent performance at unbeatable prices. Made with high-quality, breathable fabrics featuring advanced moisture-wicking technology and a comfortable compression fit, they move with your body for complete freedom during sprints, tackles, and turns.
