The striking shape of the future and the most significant design change in football helmets in over twenty years. The New Orleans Saints Full Size Revolution Helmet was designed after a four-year-study to address the causes of mild traumatic brain injury. Each Revolution Pro-Line full-sized helmet is the actual helmet NFL teams wear on the field. The Revolution design includes: an extended mandible (jaw area) protection, increased side padding, integrated facemask attachment system, weight balance redistribution, and distinguishing elliptical air vents. Helmets are made in a standard size large by the manufacturer and although they can be worn, they are intended for display only.
