If workout clothes were computers, the X-Bionic Women's Energizer Performance T-Shirt would be a T3000. Its 3D Bionic Sphere System reduces sweat production by storing small amounts of moisture near strategic parts of your body, allowing the skin to continually cool. It also takes air, heat, and moisture away from parts of your body that don't need it and conducts it to the parts that do. By compressing your muscles, the X-Bionic Energizer Shirt conserves energy and helps generate more power and endurance.
