Bell Super Air MIPS HelmetWhen it comes to mountain bike trail riding protection the Bell Super Air MIPS Helmet is at the head of the pack.  FLEX Spherical + MIPS® technology delivers incredible protection, letting you hit any trail with confidence. The Super Air MIPS Helmet provides the very best level of MTB protection but it does so while remaining light and incredibly well ventilated. This unique combination is made possible via the Fusion In-Mould design, pioneered by Bell. A tough polycarbonate outer shell is bonded directly to a multi-density energy-absorbing EPS (Expanded Polystyrene) inner, dissipating the forces involved when your head hits the dirt. This allows Bell to maintain the optimal number of vents without compromising protection. Next comes the FLEX Spherical + MIPS® system. FLEX Spherical + MIPS® ((Multi-directional Impact Protection System)The FLEX Spherical + MIPS® is the latest generation of slip-plane protection, designed to minimise the rotational forces placed on the head in the event of a crash. In doing so brain injuries are minimised. The FLEX Spherical + MIPS® has been created to address both high-speed and low-speed impacts while simultaneously dealing with rotational forces and at the same time it allows for better helmet ventilation too.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.• MIPS adds protectionCool and Fresh When You're in the FlowWhen you're in the zone and flowing down trails you're going to build up a  sweat. However, fear not the Super Air won't let you overheat. 18 vents and the Overbrow Ventilation work with the carefully designed inner airflow channel matrix to keep fresh, cooling air whooshing over your scalp. Sweat Guide padding draws moisture away from the skin for dry comfort while X-static padding, woven with silver fibres to inhibit the growth of odour-causing bacteria and fungi.
