Troy Lee Designs D4 Composite Helmet Lined up White

The D4 Composite Helmet represents the continual evolution of high-performance full-face protection, combining advanced aerospace-inspired construction, lightweight materials, and modern impact technology into a helmet built for elite BMX and gravity riders.

Using an aerospace shell design and carefully selected composite materials, the D4 Composite achieves an impressively low weight of approximately 1050g while maintaining exceptional strength and impact performance. Integrated Mips® C2 protection adds an additional layer of rotational impact safety to help reduce forces transmitted to the brain during angled impacts.

Designed for aggressive riding and racing conditions, the D4 features an advanced airflow management system that channels cooling air through a front intake system and across the internal polymer center and Power Grid side mesh structure to improve ventilation and rider comfort.

Internally, premium X-Static® and XT2® antimicrobial padding help control odor and moisture while maintaining a cleaner and more comfortable fit during extended use.
