Troy Lee Designs Adult Downhill Mountain Bike BMX Full Face Helmet with MIPS

For 40 years, Troy Lee Designs has been crafting gear for the world's fastest racers. Headquartered in Corona, California, the company has always been dedicated to pushing the boundaries of design and function.

The latest example of this relentless innovation is the D4 Composite helmet. Improving upon the class-leading D3 model was no easy feat, but the Troy Lee Designs team was up to the challenge.

The D4 Composite's shell is built using aerospace-grade materials and design, allowing it to weigh in at a mere 1050 grams without compromising strength or protection. This is achieved through the use of a composite shell and an EPP (expanded polypropylene) collarbone impact system, along with shock-absorbing chin bar pads.

Comfort and ventilation were also top priorities in the development of the D4 Composite. The helmet features a front air intake system that channels cooling air through the polymer center and power grid side mesh, keeping your head cool even during the most intense rides. The X-static and XT2 padding further enhance the interior comfort, making the D4 Composite a pleasure to wear.

Fit and adjustability were also key considerations. The helmet is available in 3 shell sizes and 3 EPS (expanded polystyrene) sizes, resulting in a total of 6 sizing options from XS to XXL. The "3D" cheek pads are anatomically shaped and can be quickly removed for easy cleaning or replacement.

Convenience features include a removable, washable Coolmax-Dri-lex comfort liner and super-light titanium D-rings, ensuring a hassle-free experience.

The D4 Composite's ventilation system is truly impressive, with 24 vents in total. This includes 10 front intake ports, 5 overhead channeling intake vents, and 7 rear exhaust ports, all working together to keep you cool and comfortable.

Ultimately, the D4 Composite is a testament to Troy Lee Designs' relentless pursuit of excellence. By combining aerospace-grade materials, cutting-edge design, and a focus on rider comfort, they have created a helmet that sets a new standard in the industry.

Whether you're a professional racer or a passionate enthusiast, the D4 Composite is a helmet that will exceed your expectations and help you push your limits on the track.
