A mountain bike helmet is strongly recommended for trail riding. The extended rear and temple coverage protects impact zones that are disproportionately common in off-road crashes where riders fall backward or sideways. The visor deflects branches, debris, and sun. While a road helmet meets the same baseline safety certifications, it lacks the coverage that makes a meaningful difference in typical mountain bike crash scenarios. The weight and ventilation penalty of an MTB helmet is minimal compared to the safety benefit.
