Lightweight Troy Lee Designs Downhill D4 Composite Helmet for Adults

The D4 Composite Helmet: Always Evolving

Improving upon the class-leading design and function of our D3 helmet was no easy feat, but we accomplished it. The D4 Composite helmet, built with an aerospace-grade shell and materials, weighs in at a mere 1050 grams without compromising strength.

The MIPS C2 system provides an additional layer of coverage for enhanced protection. For maximum comfort, the D4 Comp features a front air intake system that channels cooling air through the polymer center and power grid side mesh, keeping your head cooler during your ride.

Comfort is further enhanced by the X-static and XT2 padding, creating a much more pleasant in-helmet experience. It's important to note that this helmet is not intended for use with motorized vehicles.

Specifications: - Shell Material: Aerospace-grade composite - Claimed Weight: 2 lb 5 oz (1050 g) for the medium size - Manufacturer Warranty: 3 years - Ventilation: 10 front intake ports, 5 overhead intake vents, 7 rear exhaust ports - Fit Adjustment: D-Ring fasteners

The D4 Composite helmet represents our commitment to continuous improvement and innovation. By leveraging advanced materials and design, we've managed to create a helmet that not only exceeds the performance of its predecessor but also delivers unparalleled comfort and protection for the discerning rider.

Whether you're tackling technical trails, shredding downhill runs, or just enjoying a leisurely ride, the D4 Composite helmet is engineered to provide the confidence and security you need to push your limits and explore with peace of mind.
