Go big and stay safe.

Troy Lee Designs helmets have always had that one-off custom mystique. It could be the incredible graphics, the amazing attention to detail, or, in the case of the D3 Carbon Fiber Helmet, the sizing, which ditches the standard adjustment dials and straps in favor of a near-custom incremental sizing system. Given the helmet's fit range, 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, giving them smoother edges for a better look.

Riding around with a head covered in 15lbs of protection isn't really feasible, but the D3's shell is made from a carbon composite material that's incredibly 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 pick yourself up 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.

Incredibly light

  • Familiarity: I've used it several times

I got this helmet two weeks ago and have ridden with it a handful of times. I got the Fox rampage and tried on them both of them before returning the rampage. The fit was a bit different and the chin was longer. My buddy has a D3 from 2013 and comparing them side by side I can say that this year's model is significantly lighter. He had the large aswell and the fit is the same. I got 100% Strata goggles and those fit perfectly with the helmet.

The Benchmark Of Full Face Helmets

  • Familiarity: I've put it through the wringer

This is the full face helmet all other full face helmets want to be. Every piece of this helmet has been well thought out from the pads to the shell design to the graphics. The overall look of this helmet is amazing. You will not be disappointed with this purchase.

Changed the fit

  • Familiarity: I returned this product before using it

Helmet looks great but they have changed the fit and I picked this up to compare the fit of it to last years. For me last years was a better fit but if you were having trouble with previous sizing the change might bode well for you. Pads feel a bit thicker as well.
