Heading up the lifts for a day of race prep requires a little more protection than your average trail ride. You only get one brain, so if you're going to be a fixture on the DH or BMX circuit this year, 6D's ATB-1 Helmet makes a strong case for being the lid you trust to guard your grey matter. The full-face design comes packed full of safety features, along with ample consideration given to lightness and ventilation. The ATB-1 will protect you so well your mom will stop threatening to put you in a shred-hindering bubble. 6D achieves the ATB-1's blend of protection and practicality by using a 3K carbon fiber shell fused to its Omni-Directional Suspension liner, which consists of two separate EPS layers. Between these two layers sit 27 elastic dampers, which work to isolate the innermost layer of the helmet from forces traveling through the shell and outer layer. The layered suspension system anticipates low, medium, and high speed impacts, limiting energy transfer as much as possible. The inner liner moves along three dimensions upon impact, then resets on its own after a crash. Proprietary technology aside, the system addresses serious risks to riders, separating the ATB-1 from more recreational models. Towards the practicality end, 6D took as much careful consideration to ventilation and construction as it did to safety for the ATB-1. It carved out ten intake ports, 13 transfer ports, and four exhaust ports to create its aggressive airflow system, guaranteeing fresh air reaches your head while you ride without compromising structural integrity. An anti-odor liner adds comfort along the inside of the helmet, with padding and protection along the jaw, face, and cheeks, as well as a cutaway for freedom of movement along the collar bone. Plus, both the cheek pads and visor were built to be easily released in an emergency.
