Incorporating all of the benefits of Omni-Directional Suspension technology this is the most advanced full-face helmet available in the marketplace today. Each ATB-1 incorporates a state-of-the-art 3K carbon fiber shell mated to 6D’s exclusive dual-layered ODS EPS protective liner. This combination of materials and technology provides the best possible protection against angular acceleration and low-threshold energy transfer from crash impact. The ATB-1 is the gold-standard of Down Hill, Enduro, and BMX competition helmets and exceeds the ASTM F-1952-10, and CPSC 16 CFR1203 safety standards (US), and EN1078 (Europe).
