Troy Lee Designs D4 Composite MIPS Helmet White/Red

Lightweight full-face protection meets advanced ventilation thanks to an aerospace-inspired composite shell paired with 20 intake and exhaust ports that channel cooling airflow through the helmet. The D4 Composite Helmet balances durability and comfort in a lightweight 1000g-1150g design built for demanding riding.

Troy Lee Designs equips the D4 Composite Helmet with the Mips® C2 rotational impact protection system and added EPS for improved impact performance. X-static® and XT2® antimicrobial padding manage moisture and odor, while emergency-release cheek pads and stainless steel D-ring hardware enhance fit and safety.
