6D ATR-1 Chaos Helmet

A true breakthrough in helmet technology, the 6D ATR-1 off-road helmet incorporates revolutionary Omni-Directional Suspension ( ODS ) technology which is a patent-pending kinetic energy management solution. We haven't seen anything like this before, but preliminary results show a dramatic reduction in low-threshold engery transfer for 6D Helmets.

ODS is designed to protect your brain over a broader range of impact energy, particularly low–threshold energy prevalent in most accidents. Low-threshold impact energy is the primary cause of concussion and second impact syndrome. Independent laboratory testing also confirms a significant reduction in angular acceleration energy with ODS. Angular acceleration is the primary cause of rotational brain injury, which is a potentially deadly and life-changing impairment.

The improved performance of 6D’s exclusive ODS technology can reduce the likelihood and propensity of concussion over traditional helmet designs. Although no helmet can protect you from all potential impacts or injury, the 6D ATR-1 was engineered to provide active free-motion capability within the helmet’s protective liner and exceed current relevant helmet standards.

The ATR-1's exclusive Air Gap cooling system incorporates 13 interior transfer ports, 8 intake ports, and 5 exhaust ports. The amount of time and energy devoted to moving air through 6D Helmets is second to none. Extensive front-to-back ventilation channels are fed by 3 large upper eyeport intake ports and 2 aggressive brow intake ports. These intake ports combined with chin bar vent openings channel cool air into the ATR-1’s air gap flushing hot air and moisture out the rear of the helmet.

Premium Quality Helmet This a Premium Quality Helmet. Fit & FInish is what you'd expect from a premium top of the line helmet. Safety features far surpass that of any other helmets I have worn. March 9, 2015
Best Helmet I've ever owned Bought my ATR1 at a local dealer because they owed me a 350 dollar credit from an old warranty claim, otherwise I'd have bought it from zilla... That being said, this is the best fitting helmet I've ever owned. The bag is awesome, the fit and finish of the helmet is world class. I'm truly amazed at how light it is. It fits the Sena SMH10R kit perfectly, almost like it was made for it. Great airflow, it was 88 today and I just love the combination with the helmet and my 100% racecraft goggles. I ordered the yellow, the only drawback is it is almost like a neon greenish yellow, not the plain yellow I was shooting for. I can't say enough good things about this helmet. May 13, 2014
The best Top lid, feels great, feel a lot safer, can see more enabling me to ride faster April 25, 2014
best helmet on the market with the new technology 6D has, with their shock absorber system, Im less likely to get a concussion with smaller accidents. stoked. Great Helmet! October 14, 2013

6D Helmets fall into the nuetral or intermediate oval headshape category. While the shell itself is slightly larger, due to the space needed to contain the omni-directional suspension (ODS) system, their fitment is rather true to size. Using the size chart above yields accurate results.
