Troy Lee Designs SRAM D4 Composite MIPS Helmet – Ultimate MTB Protection Redefined

Engineered for mountain bikers who demand peak performance, the D4 Composite MIPS Helmet elevates safety and comfort with aerospace-grade materials. At just 1050 grams, it delivers unmatched strength without the bulk, making it ideal for endurance trails and aggressive downhill rides.

Why Riders Choose the D4 Composite:

• Advanced Safety: MIPS C2 technology redirects rotational forces during impacts, while the reinforced EPS liner and optimized headform enhance crash protection.
• Superior Ventilation: 20 high-flow ports and a front-to-back airflow system keep you cool on steep climbs and technical descents.
• Customizable Fit: Full incremental sizing and quick-release 3D cheek pads ensure a snug, secure fit for all head shapes.
• Rider-Focused Comfort: X-static® anti-microbial padding wicks sweat, and shock-absorbing chinbar pads reduce pressure during long rides.

Built for the Trail:

• Integrated cavities for seamless audio system compatibility (great for trail navigation or music).
• Lightweight stainless steel D-rings for durability without added weight.
• Includes a premium drawstring helmet sock for storage and transport.
