Small helmet. Big features. The MX426s shell is made from LS2s proprietary HPTT composite. Its lightweight to help the rider avoid fatigue during a long moto or a long trail ride. Flow-through ventilation keeps them cool when the competition heats up. The cheek foam is cut from one solid piece of high quality foam using LS2s 3D Laser Technology for a precise fit that will stay in place. Mom will appreciate that the comfort padding is made from a technical fabric that resists bacteria and odor, and the liner is fully removable and washable so you can keep it fresh (always hand wash and air dry liners). The LS2 MX426 offers features youd expect to find on a high performance off-road helmet at a price that will make you very happy. Covered by a 5-year warranty against defect in material and workmanship. DOT approved.
