Go big and go home.

Sending it like a boss and landing on your face doesn't necessarily mean you'll need to spend a few months sipping burgers through a straw if you were clever enough to pull the Troy Lee Designs D3 Composite Helmet over your dome before you sent it. The D3 Composite is the same as the top-shelf D3 Carbon, but as the name suggests, features a shell made from composite instead of superlight carbon. It ditches the standard adjustment dials and straps in favor of a near-custom incremental sizing system, so you're virtually guaranteed a helmet that nestles snugly around your dome, regardless of whether the dome in question happens to be enormous, petite, or somewhere in between.

The outline of the D3 is the same as the old D2, but Troy Lee rejiggered the shape to improve its fit and feel. There's more EPS foam in the frontal areas, so you'll be safer when you face plant, and the new 3D cheek pads are contoured to fit around your jaw and lovely mug for a more secure fit and better protection. Troy Lee also redesigned the visor and front trim with smoother edges for a sleeker look.

Riding around with a head covered in 15lbs of protection isn't really feasible, but the D3's shell is made from a composite material that's seriously strong and surprisingly light. Dual-density shock pads line the helmet and absorb smaller impacts, so you won't crack the primary EPS liner in a little fall and have to buy yourself a new lid. The D3's removable, washable liner incorporates Coolmax and Dri-Lex technologies, which wick moisture, cool your dome, and fight odor. A host of 20 vents pulls air across your head and forces it out the back for efficient cooling, the adjustable visor is held in place with titanium hardwear (and can be swapped out for the included second option), and the corrosion-resistant D-ring fastener cinches the D3 around your chin to keep it from bouncing off when you go a little bit bigger than you planned.

  • Conquer the big stuff in this full-face enduro helmet
  • Composite construction is lightweight and durable
  • EPS foam protects front of your head
  • 3D cheek pads provide a contoured fit around your jaw
  • Removable, washable liner is breathable and cool
  • Adjustable visor and D-ring fastener lend a customizable fit

Great fit

  • Familiarity: I've used it once or twice and have initial impressions

A little heavier than the carbon but also cheaper. Same great fit though. Tons of colors to choose from as well.
