Troy Lee Designs Downhill D4 Camo Full Face Mountain Bike Helmet - Adult Mens Womens Unisex

Aerospace-grade composite is the material used for the shell of the D4 Composite helmet, which was designed to improve upon the class-leading design and function of its predecessor, the D3 helmet. Despite the enhanced capabilities, the team was able to achieve a weight of 1050 grams without compromising any strength. To provide an additional layer of coverage, the MIPS C2 system has been incorporated.

For the comfort of the rider, the D4 Comp helmet features a front air intake system that channels cooling air through the polymer center and power grid side mesh, effectively keeping the head cooler during the ride. The use of X-static and XT2 padding further enhances the overall comfort and experience.

It is important to note that this helmet is not intended for use with motorized vehicles.

The claimed weight of the medium-sized helmet is 2lb 5oz (1050g), and it comes with a 3-year manufacturer warranty. The ventilation system includes 10 front intake ports, 5 overhead intake vents, and 7 rear exhaust ports, while the fit adjustment is facilitated by D-Ring fasteners.

In summary, the D4 Composite helmet is a result of the team's efforts to improve upon the design and function of the previous D3 model. With its aerospace-grade composite shell, MIPS C2 system, and advanced ventilation and padding features, the D4 Comp offers enhanced protection and comfort for the rider, all while maintaining a lightweight construction.
