Troy Lee Designs D3 Bike Helmet

We didn't even know it was possible to improve on the D2, but the Troy Lee Designs D3 Bike Helmet has exceeded not only safety standards, but our wildest imaginations. With twice the ventilation and adjustability, the D3 is lighter, prettier, more comfortable, and most importantly safer than anything you could possibly pop on your top. With a modern carbon/composite shell and remarkably-high air flow, the Troy Lee Designs D3 Bike Helmet will make you feel like you're flying, and protect you when gravity kicks in again.
