The Troy Lee Designs D3 Fiberlite Bike Helmet is designed for lightweight and breathable protection against sudden impact on-trail. An impact absorbing EPS liner adorns the interior of the helmet, endowing the D3 Fiberlite with enviable defense against impact forces. Designed to spread traumatic energy across a wider surface area, the EPS liner protects the brain from a sudden hit in a localized area. 20 high flow intake and exhaust ports maximize ventilation throughout the helmet, ensuring this full-face fiberglass shield never gets too stifling. Equipped with 3D cheek pads, a breakaway visor, and a quick-drying interior, the Troy Lee Designs D3 Fiberlite Bike Helmet prioritizes comfort and safety above all else – maximizing performance in all conditions, on all terrain.
