Features ECE 22-05/ DOT approved Adaptive Impact System Tri-weave composite shell, made from carbon fiber, Du Pont™ Kevlar® & fiberglass, producing a lightweight shell with superior penetration resistance Impact Energy Cells made from RHEON, the Impact Energy Cells maximize absorption of low speed linear & rotational impacts, reducing forces transmitted to the brain Conehead® Dual-density Expanded Polystyrene (EPS) Technology provides a softer liner whereby the cones help manage or absorb an impact force more efficiently Six critical zones have been fine-tuned for a progressive response to low speed & high-speed impacts Expanded volume EPS means strategic areas of the helmet have more impact absorbing EPS, more suspension between your head & the ground Expanded Polypropylene (EPP) chin bar creates an additional element of impact mitigation, & is used in the chin bar for its superior damage resistance, & energy absorbing properties Clavicle shell relief zone creates a soft zone filled with EPS & EPP to aid in reducing clavicle injuries Custom molded rubber trim with integrated nose guard Weight 1340 grams +/-50 gr. (size MD/LG), 2.9 pounds +/-0.11lb (size MD/LG) Comfort liner & quick release cheek pads are made from washable moisture-wicking, anti-microbial material True Functional Ventilation (TFV)-When in motion air is forced through multiple air intake vents, then passed through aligned vent channels in the EPS & exits out multiple rear exhaust vents Included soft fleece helmet bag Note Please be aware, as long as nothing else is written in the item description: All helmets will be delivered only with the ECE certification by default
