Troy Lee D3 Full Face Multi-Sport Helmet: Dual Density Shock Pad System

With the D3 fullface carbon fiber multi-sport helmet, Troy Lee Designs introduced the Dual Density Shock Pad System, which uses strategically positioned multi-impact shock pads on the inside surface of the single-impact expanded polystyrene (EPS) liner. These pads provide a primary impact material that is lower density than the EPS liner, which has deep channels for venting. This shock pad layer provides low-speed impact absorption and improved comfort and durability for the frequent lighter hits that might otherwise cause damage to the EPS interior.

The Troy Lee Designs D3 full face mountain/bmx bike helmet is a high-end lid loaded with plush features certain to please serious bmx and downhill mountain bike riders and skiers/snowboarders, but perhaps more impressive are the multiple safety standards the D3 full face helmet meets.


Troy Lee Designs: More Than Just a Pretty Face

Troy Lee helmets are known for their gorgeous, intricate, mega-cool graphics. But equally important is the company’s quest for thoughtful design that combines functional an aesthetic objectives. In other words, Troy Lee makes helmets that not only look good but are designed to keep you safe and comfortable. The company began in the late 1970s when a teenaged Troy Lee, a racer himself, started making custom-painted helmets in his garage. The rest is history.
