The D3 Fiberlite features a budget-friendly price point but incorporates many of the racing-derived features found on its top-shelf D3 Carbon/Composite siblings. The helmet sources a lightweight fiberglass shell with wind-tunnel proven aerodynamics and efficient ventilation system. 
The D3 Fiberlite also delivers a comfy, secure fit from its 3D cheekpads, as well as TLD’s signature styling and attention-grabbing FACTORY race team graphics. Thanks to the D3 Fiberlite the most decorated helmet in professional racing is now available for riders who crave factory performance on a privateer budget.
