C4 Pro Magnitudo Helmet With the addition of a newly developed seamless interior liner, the C4 Pro takes the C4 to the next level. The unmistakable German engineering and radical, compact shell design of the C4 Pro Helmet set the new standard for premium modular touring helmets. Featuring a new liner and 2 reworked shell sizes (XS-LG, XL-3XL), the lean form of the C4 Pro Helmet has been extensively tested and aerodynamically optimized for both stability at speed and low weight to minimize fatigue on long tours. Discover a riding experience similar to sitting in the cabin of a luxury German sports car. The C4 Pro Helmet is designed for riders who accept only the best, and can appreciate the difference. Note: Helmet is slightly narrow around the chin bar and may not fit comfortably if you have a round face or longer chin. Features: Aerodynamically tuned shell to mitigate fatigue Integrated one touch sun visor ShinyTex interior Complex multichannel ventilation system Integrated antenna Pre-installed speaker and microphone Plug & Play prepared for the SC1 communication system Extra large anti fog lens insert: Wide field of vision in any riding position 2 shells: XS-LG, XL-3XL DOT approved Outer Shell: The outer shell of the C4 Helmet is constructed using an innovative proprietary method called Direct Fiber Processing (DFP). A continuous strand of glass yarn is robotically precision cut and blown outward into position in the mold. An exacting amount of resin and heat are added under high pressure, yielding a shell of superior strength that is no thicker in any one area than it needs to be. DFP Glass fiber heat-formed shell Glass fiber with a special resin is compressed in a vacuum at high pressure to form a helmet shell which is exceptionally sturdy Perfected aerodynamics for high speed stability Directionally stable No oscillatory tendency No buffeting Spoiler integrated into the helmet shell/neckroll SC1 System: The C4 Helmet comes equipped to accommodate the SC1 System (sold separately). To guarantee ideal reception, the C4 Pro comes out of the box with integrated antennae to boost reception, as well as pre-installed speakers and microphone. Integrated antennae for optimum reception at all times Pre-installed speaker and microphone Plug & Play prepared for the SC1 communication system EPS: The EPS foam impact liner uses a sectional, multi-part design to ensure the highest shock absorption for various impact scenarios. This complex segmentation guarantees enhanced force absorption and distribution. Made of specially-optimized EPS foam Complex multi-zone sections allows optimal shock absorption Inner Lining: The comfort liner of the C4 Pro Helmet utilizes ShinyTex, a fabric inherently antibacterial, washable and fast-drying. A seamless headliner and integrated spectacle channel ensure maximum comfort for all riders. ShinyTex fabric Antimicrobial and allergen-free Removable/Washable Quick drying Optimized secure fit Variable venting for effective ventilation Ventilation: The C4 Pro features an intricately designed multi-channel ventilation system inside the helmet shell, resulting in extraordinarily quiet, substantial air flow. Inlets in the forehead and chin area ensure that you keep a cool head. Face Shield: Extra large anti fog lens for the widest possible field of vision, both centrally and peripherally through the oversized eyeport. Extra wide viewport Anti-fog lens-ready face shield Anti-fog lens insert included
