POC Cularis MTB Helmet Find a new level of confidence on every trail The POC Cularis is the lightest trail helmet POC has ever made - and it was built to stay that way without cutting corners on protection or ventilation. Extensive CFD modelling, a process more commonly reserved for road helmets, was applied to the Cularis's airflow design so it stays cool grinding up long climbs and ripping through fast, technical singletrack. Extended protection zones, Aramid bridges between the liner and shell, and Mips Air Node rotational impact protection ensure the Cularis is as serious about safety as it is about keeping you cool. A patented breakaway peak, adjustable 360deg fit system, Fidlock(R) magnetic buckle, and integrated eye garage make the day-to-day details effortless. Features Extensive CFD-optimised ventilation designed with computational fluid dynamics simulations to provide an incredible amount of cooling airflow Mips Air Node system a low-friction layer laminated to the comfort padding that works to redirect rotational impact forces during certain crashes Aramid bridges between the liner and shell improve structural stability and penetration protection throughout the helmet Patented breakaway helmet peak engineered to break away in a frontal impact, directing forces away from the head; adjustable for sun and rain protection mid-ride Extended protection zones over the temples and around the back of the head for coverage where trail impacts are most likely to occur Adjustable 360deg fit system with no pressure points, designed to fit securely across a range of head shapes Fidlock(R) magnetic buckle for quick, effortless one-handed chin strap closure Eye garage in the front ventilation ports for secure, scratch-free sunglasses storage mid-ride POC Whole Helmet Concept(R) each element designed together from a rider's perspective, balancing protection, comfort, and ventilation SPECIFICATIONSWeight360g (Size S) / 350g (Size M) / 430g (Size L)MIPSMips Air Node Fit System Adjustable 360degSafety Certifications CPSC 1203, EN 1078Intended Use Trail, Downcountry, Enduro, Commute Sizing Size XSSMLHead Circumference (in)19 - 20. 5"20 - 21. 5"21. 5 - 23"23 - 24. 5"Head Circumference (cm)48 - 52cm51 - 54cm55 - 58cm59 - 62cm | Poc | Cularis Helmet Men's | Size Large In Olivine Green Matt/thulite Pink Matt
