Troy Lee Designs Downhill D4 Composite Helmet for Ventilation and Lightweight (Adult Unisex)

Aerospace-grade composite material is used to construct the shell of the D4 Composite helmet, which has been designed to improve upon the class-leading features of its predecessor, the D3 helmet. Despite the enhanced design and functionality, the team has managed to keep the weight of the D4 Composite down to 1050 grams, without compromising on strength.

The D4 Composite helmet incorporates the MIPS C2 system, which adds an extra layer of protection. For enhanced comfort, the helmet features a front air intake system that channels cooling air through the polymer center and power grid side mesh, helping to keep the rider's head cooler during the ride. The interior of the helmet is lined with X-static and XT2 padding, providing a more comfortable and enjoyable experience.

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

The key technical details of the D4 Composite helmet are as follows:

Shell Material: Aerospace-grade composite Claimed Weight: [medium] 2lb 5oz (1050g) 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 is the result of the team's relentless efforts to improve upon the already impressive D3 helmet, offering enhanced design, functionality, and comfort, without sacrificing weight or strength.
