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.
Key Features
- Mips® C2 Protection System: Rotational impact brain protection designed to reduce forces transferred to the head during angled impacts.
- Composite Shell Construction: Aerospace-inspired shell design balances durability and weight from 1000g-1150.
- Advanced Ventilation System: 20 high-flow intake and exhaust ports promote consistent cooling airflow.
- Enhanced Impact Structure: Added EPS and revised headform shape improve overall impact performance.
- Emergency-Release Cheek Pads: Quick-release contoured 3D cheek pads support safe helmet removal when needed.
- Antimicrobial Interior Padding: X-static® and XT2® fabrics help manage moisture, bacteria, and odor.
- Audio Integration Compatibility: Purpose-built internal cavities allow audio system integration.
- Secure Chinstrap Hardware: Stainless steel D-ring chinstrap closure provides durable retention.
- Safety Certifications: Meets CPSC 1203, CE EN1078:2002+A1:2012, ASTM F1952-15, ASTM F2032-15, and ASTM F2040-11 standards.
