POC Kortal Race MIPS MTB HelmetThanks to its cutting edge safety technology, including MIPS, RECCO® Reflector and NFC Medical ID chip, the POC Kortal Race MIPS MTB Helmet keeps yu safer when you're pushing your mountain biking limits. For big mountain trails, local trail centre loops or crushing it at an Enduro race, the Kortal Race MIPS MTB Helmet has been created to keep you as safe as possible when it all goes a bit wrong. The extended protection zones give outstanding coverage of your head, absorbing impacts no matter which way you're ejected from your bike. When You Can't Keep Biking. This Helmet Keeps Protecting.When you’re mountain biking, crashing is a part of the game. It’s how you progress. Get better. Push boundaries. However, there may be a time when you’re not able to simply dust yourself down and carry on riding. It’s here the Kortal Race MIPS comes in. It features an 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.MIPS Integra SolutionThe MIPS Integra system brings together POC's 'whole-helmet' safety and design ethos with the brain-protecting technology of MIPS. This holistic approach sees every detail of the helmet engineered to work in harmony with each other, giving you new levels of integrated safety, comfort, ventilation, fit and function.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.Ready to RollNot just safe, the Kortal Race is also full of features to make your ride better. With an easy to adjust fit system, you can get comfort levels dialled in perfectly and the adjustable peak lets you tailor the sun and rain protection to your liking. The peak is adjustable, allowing you to pull up goggles and sunglasses easily. If you do wear goggles, POC have ensured no ventilation ports are covered by the strap, maintaining excellent airflow at all times. The helmet is also certified to the Dutch NTA 8776 electric bicycle helmet standard, the only such standard in the world.
