Helmet MTB Trail 3.0 The one trail helmet you will ever need with premium head and brain protection. A lightweight all-purpose MTB helmet for trail riding, cross country training and back country or gravel adventures. This helmet is well ventilated with maxiflow air channels and the Dri-LexA(R) liner is washable, moisture wicking, anti-odor and breathable. Featuring convenient sunglasses docks above the visor for easy storage on and off the bike. The MTB 3.0 Trail helmet also has the much-liked Fidlock buckle for easy use with gloves on. The MTB 3.0 Trail helmet has a brand new Powerbridge construction design making it very safe, well ventilated and stylish. Featuring 360 Turbine Technology, the helmet is lined with turbines which are 360 moving discs constructed from an energy-absorbing foam and material. Because these Turbines can move 360 (omnidirectional), this technology has two exclusive advantages: namely the reduction of rotational acceleration to the head and brain and the absorption of energy upon impact at concussion level. Ride safe, while looking and feeling cool with the MTB 3.0 trail helmet.
