Leatt MTB AllMtn 3.0 HelmetThe Leatt MTB AllMtn 3.0 Helmet has been created to offer all-round comfort and it's stacked with features for boosting safety and confidence when you're mountain biking.The MTB AllMTN 3.0 Helmet features a lightweight polymer shell to brush off the dings and bumps from overhanging branches. This durable outer shell is directly moulded to the impact-absorbing foam core. Should you be unfortunate enough to crash, this core soaks up and dissipates impact forces. The 3.0 also features Leatt's 360 ̊ Turbine Technology.360 ̊  Turbine TechnologyThe 360 ̊ Turbine Technology is focused on reducing the damaging effects of a crash on your brain. It works via 360 ̊moving discs, all made from an energy-absorbing material. These impart a reduction of rotational acceleration to the head and brain by up to  40%. The system also improves the absorption of impact energy  - it reduces peak brain acceleration by up to 30% at the impact speeds associated with concussion. Cool and ComfortableRowdy riding will soon see you sweating. But with a total of 20 vents, you'll enjoy excellent airflow, letting in cool air and allowing sweat to escape. Inside, the moisture-wicking padding also adds to the excellent comfort levels. They're anti-odour and washable too, letting you keep everything fresh for every ride. Features:Lightweight polymer shellIn-moulded impact foam for superior energy absorption360-degree Turbine Technology - Reduces forces associated with concussionAdjustable visor with breakaway function for rotational impact force reductionMaximized ventilation with 20 vents effective even at low speedsFidlock magnetic closure systemSunglasses dock port for easy, secure storageMoisture-wicking, breathable, anti-odour and washable inner linerCertified and tested: EN1078Weight: from 350gBuy Leatt Protection from Chain Reaction Cycles, the World's Largest Online Bike Store.
