The ATB-2T Ascent Mountain Bike Helmet incorporates 6D's fourth generation of ODS system, mating a multi-impact EPP inner liner to an in-molded EPS outer liner and outer PC shell. This combination of materials combined with 6D's award winning technology provides unmatched performance in a lightweight fully ventilated trail helmet. A unique fit system combined with Ionic+ anti-microbial fit liner and a Fidlock closure further improves safety and rider comfort.
The ATB-2T received 6D's most optimized and efficient ODS system to date. The latest version of the technology is a culmination of over 10 years of research and development. The light weight system is highlighted by a new Expanded Polypropylene (EPP) multi-impact inner liner design featuring damping towers and a series of elastomeric isolation dampers. This combination provides progressive loading of the ODS system during impacts. These parts in conjunction with a traditional Expanded Poly Styrene (EPS) outer liner provide the most complete energy management solution available today.
