Troy Lee Designs Downhill D4 Composite Reverb Helmet for Ventilation and Lightweight MIPS EPP EPS - Adult Unisex

The D4 Composite helmet, an evolution of our class-leading D3 design, was not an easy feat to accomplish. Constructed with an aerospace-grade shell and materials, we were able to achieve a weight of 1050 grams without compromising any strength. The inclusion of the MIPS C2 system provides an additional layer of coverage for enhanced protection.

Comfort was a key priority in the development of the D4 Comp. 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 during your ride. The X-static and XT2 paddings ensure a much more pleasant experience inside the helmet.

Designed with an aerospace-grade composite shell, the D4 Composite helmet boasts a claimed weight of 2lb 5oz (1050g) in the medium size. Backed by a 3-year manufacturer warranty, this helmet is not intended for use with motorized vehicles.

The ventilation system of the D4 Comp is meticulously engineered, with 10 front intake ports, 5 overhead intake vents, and 7 rear exhaust ports, ensuring optimal airflow and temperature regulation. The fit is adjustable using D-Ring fasteners, allowing you to achieve a secure and comfortable fit.

In summary, the D4 Composite helmet represents the culmination of our relentless efforts to improve upon the already impressive performance of the D3 model. With its aerospace-inspired design, advanced materials, and thoughtful comfort features, the D4 Comp continues to push the boundaries of what a high-performance cycling helmet can be.
