BBB FIRLayer undershirt

FAR Infrared technology makes this base layer the best protection in the worst conditions. Due to the microscopic ceramic particles in the fabric, infrared heat from the body is reflected back on the skin for an extra dimension in insulation. Long sleeves, warm but thin material and a high collar; all features to make this a great choice for when it gets rough outside. Besides protection, the special ribs in the material give your body the support it needs.
