Viconic Protection - A historic approach to head protection focused on safety first. Focused impact zones in the occipital lobe and temples are reinforced with a lightweight diffusion plate called Viconic. Viconic absorbs multiple impacts both linear and twisting and spreads them across a wide surface area. The Diffusion of force is not one material's responsibility. The one-piece shell and EPP foam filling liner is the core of safety, forming a lightweight barrier that helps provide protection against catastrophic injury.
