Engineered for aggressive riders who demand both safety and performance, the D4 Composite Stealth helmet combines aerospace-grade composite construction with advanced impact protection.

Key Features for Maximum Performance & Safety
- MIPS C2 Brain Protection: Reduces rotational forces during angled impacts, a critical feature for high-speed crashes.
- Optimized Ventilation: 24 strategically placed vents (10 front, 5 overhead, 7 rear) keep airflow efficient, preventing overheating on intense rides.
- Precision Fit System: 3D-molded cheek pads and a 7-anchor-point headliner ensure a snug, comfortable fit across six sizes (XS–XXL).
- EPP Collarbone Protection: Reinforced lower shell design minimizes impact forces in crash-prone shoulder/collarbone zones.
- Anti-Microbial & Quick-Dry Liner: XT2® and X-Static® fabrics resist odor and wick sweat for long-wearing comfort.
Built for the Toughest Riding Conditions
Certified for DH MTB (ASTM F1952), BMX (ASTM F2032), CPSC 1203, and CE EN1078, this helmet meets rigorous safety standards for competitive racing and freeride adventures. The included drawstring bag makes transport easy, while the 3-year warranty underscores its rugged reliability.
