POC Otocon Race MIPS Helmet 2022 - Hydrogen White-Uranium Black Matt - L}, Hydrogen White-Uranium Black Matt
  • £225.00
  • RRP £300.00
  • Saving you £25

POC Otocon Race MIPS HelmetThe POC Otocon Race MIPS Helmet proves that a full-face helmet needn't weigh you down in order to keep you protected. At just 750 grams but packed with features, it's got all you need for rowdy mountain biking. Safety FirstMountain biking is tough on both the body and your equipment. And none more so when you're unfortunate enough to crash. The Otocon Race MIPS Helmet is here to keep you safer when it all goes a bit wrong. The first line of defence comes via the Otocon's dual-material construction. In the event of an impact to the head, a combination of EPP foam lower and EPS foam upper provide the perfect degree of energy dissipation, helping prevent injury. A tough and durable outer shell works with moulded Aramid bridges to enhance both structural strength, integrity and improve penetration protection. This is one tough helmet. While the peak is great for keeping out sun and rain, it's also safe, breaking away from the helmet body in a crash, reducing damaging forces upon your neck. Meanwhile, the chin guard features a removable grill, offering protection from mud and dirt in winter but easily removed to boost airflow in warmer weather. MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Let the Otocon do the TalkingWhen you’re mountain biking, crashing is a part of the game. As they say, if you're not crashing, you're not progressing. However, there may be a time when you’re not able to simply dust yourself down and carry on riding. It’s here the Otocon Race MIPS Helmet excels. It features a twICEme® NFC Medical ID chip, letting you store vital medical and emergency contact details. With an NFC-enabled smartphone first responders can read the chip and make the best treatment decisions there and then.And if that wasn’t enough, a RECCO® Reflector lets emergency services scan for you should you become lost on a backcountry mountain biking adventure.Cool ComfortBe it downhill runs or a tough enduro, it's all very well feeling protected but you certainly don't want that to compromise comfort. Thanks to the excellent ventilation, with internal air channels to maximise airflow, you'll enjoy all-day mountain bike riding comfort.FeaturesDual-material liner - EPP in the lower part of the helmet improves durability and sustainability, while an EPS upper keeps weight lowInjection-moulded liner - lower part of the liner features an injection-moulded cage for extra strength and stabilityMIPS Brain Protection System gives improved rotational impact protectiontwICEme® NFC Medical ID - gives instant access to vital medical and emergency contact detailsRecco reflector - helps rescue services easily and quickly locate you if something goes wrongAramid Bridges - moulded to the helmet liner to enhance structural stability and improve penetration protectionRace Lock integrated adjuster - easy to find a comfortable, secure fitBreakaway peak - will break away in a fall to reduce potential neck injuryInnovative airflow channels - channels through the helmet work to keep the head cool at both high and low speedsRemovable cheek pads - can be easily removed after a crashRemovable grill - chin piece grill protects the face from mud splashes - can be removed for better airflow in warmer, drier conditionsWeight: 730g (M)Certification - EN 1078Shop all MIPS helmets - Click hereBuy POC Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.
