Troy Lee Designs D4 Composite Stealth Helmet Olive

D4 Composite is the legendary and iconic Downhill, Freeride and BMX racing helmet by Troy Lee Designs designed to revolutionize the union between technology, protection and artistic design. Featuring an outer shell made of composite fibers, this helmet offers an ultra-light and ventilated structure. Thanks to MIPS technology, D4 Composite ensures optimal protection and safety for all kinds of adventures.

MIPS TECHNOLOGY
The new D4 MTB bike helmet is equipped with the MIPS C2 protection system, an acronym for Multidirectional Impact Protection System, a revolutionary technology that reduces and slows down the amount of energy transferred to the head in angular impacts. The inclusion of MIPS in Troy Lee Designs helmets drastically reduces the rotational forces and consequently the risks related to possible concussions. D4 is also equipped with the Collarbone Suspension System, designed to ensure that the force and pressure resulting from any impacts on the shoulders are distributed evenly, rather than concentrating in a single point.

MAXIMUM VENTILATION
The D4 Composite helmet ensures maximum ventilation thanks to the 24 ventilation holes, 10 front inlet holes and 5 above the head. 7 exit holes.

The interior in X-static® and XT2® ensures an antibacterial and anti-odor treatment.
