Extensive coverage meets superior ventilation with the POC Coron Air MIPS. It's a helmet that's been in our gear closet for a while, and we choose it over most full-face helmets when we're racing down the mountain and putting it all on the line. See, while most full-face helmets are built with an EPS liner that's really only rated for a single impact, the POC Coron is built with a tough fiberglass shell and a multiple-impact EPP liner. This gives us an extra level of protection so we can keep charging through the riding season with confidence. For the most recent model, POC phases out their SPIN technology in favor of a MIPS liner to protect against lower-speed rotational impact forces.POC's premier full-face for downhill and enduro ridingOptimized ventilation keeps us cool and low and high speedsMulti-impact EPP liner offers superior protection over EPSRemovable cheek pads for better ventilation on transfer stagesHelmet is developed in conjunction with POC professional athletesBreakaway visor offers increased safety in the event of a crashNew MIPS liner replaces POC's spin technologySpecially formed ear chambers minimize negative effects on balance and hearingShell MaterialfiberglassMultiple ImpactEPPAudio CompatiblenoVentilationoptimized ventilation in shellFit Adjustmentadjustable strap with buckleVisoradjustable, breakawayFull FaceyesCertificationsComplies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older, EN1078, ASTM F1952Claimed Weight[medium] 2lb 9ozActivitydownhill, enduroManufacturer Warranty1 year
