Troy Lee Designs D4 Composite Helmet - Outstanding design & best protection

Many helmets claim to be the icon, the legend, the undisputed champ-but there is only one truth. 
The Daytona, D2 and D3 series of helmets changed the entire state of play and redefined the marriage between technology, safety and artistic design. That idea is reborn with the launch of the D4 Carbon and Composite and will yet again...change everything.
