Always Evolving: The Evolution of the D4 Composite Helmet

Improving upon the acclaimed design and functionality of our D3 helmet was no small feat, but with the D4 Composite, we've achieved just that. Crafted with an aerospace-inspired shell and utilizing advanced materials, we managed to achieve a weight of 1050 grams for the D4 Composite without compromising on strength. The integration of the MIPS C2 system further enhances its protective capabilities, adding an extra layer of coverage.

In terms of comfort, the D4 Comp incorporates a sophisticated air management system. A front air intake system directs cooling air through the polymer center and power grid side mesh, effectively regulating temperature and keeping your head cool throughout your ride. The interior is lined with X-static and XT2 padding, ensuring a plush and hygienic environment inside the helmet.

It's important to note that the D4 Composite helmet is designed specifically for non-motorized vehicles and is DOT certified for safety. It meets or exceeds both FMVSS-218 and DOT safety standards, assuring top-notch protection.

Key features of the D4 Composite include:

• TeXtreme Spread Tow Carbon Fiber Shell: Known for its lightweight yet strong properties, enhancing overall durability.

• Customized Fit: Available in 3 shell sizes and 3 EPS sizes, offering a total of 6 size ranges from XS to XXL, ensuring a precise fit for various head sizes.

• Optimized Ventilation: Equipped with a total of 24 vents strategically positioned for maximum airflow. This includes 10 front intake ports and 5 overhead intake vents that direct air over the top of your head, complemented by 7 rear exhaust ports to expel heat efficiently.

• Enhanced Interior: The X-static Quick Dry XT2 liner not only enhances comfort but also aids in moisture management, keeping the interior dry and fresh.

In conclusion, the D4 Composite helmet represents a significant advancement in helmet technology, blending cutting-edge materials with innovative design to deliver unparalleled performance and comfort. Whether you're cycling, skating, or engaging in any non-motorized activity, the D4 Composite ensures you stay protected without compromising on style or comfort.
