Although many look forward to the D3 Troy Lee Helmets for 2010, the D2 is still a nice lineup, and can save you a couple dollars, but the retail price still ranges depending on the graphics. Materials used on the Troy Lee Designs 2010 D2 Helmets are carbon and composite shell, while the D2 is a bit lighter than the D3, but if you want a helmet that allows your head to breathe and protected more, the D3 is the way to go.
What you can expect with the D2 Troy Lee Designs 2010 Helmets are seven intake vents, four outake ports, D-Loop fastening, titanium peak screws, and a pad liner you can take out and clean. As you can see, different colors and graphics are available, with the Love Hate helmet grabbing the most attention. The carbon helmets come with a SE helmet bag, and the helmets start at $450.
