Troy Lee Designs D4 Composite Mirage MIPS Helmet

Master Precision Meets Extreme Performance
For downhill warriors and BMX trailblazers seeking unmatched protection without sacrificing speed or agility, the Troy Lee Designs D4 Composite Mirage MIPS Helmet redefines race-day essentials. Designed for professional cyclists tackling ASTM-certified DH MTB and BMX courses, this lightweight marvel combines cutting-edge safety tech with breathable comfort—perfect for high-intensity rides where every gram counts.


Revolutionary Safety & Lightweight Design

  • Aerospace-Grade Composite Shell: Weighing just 1050g (±50g for size M), this is our lightest composite downhill/BMX helmet yet—engineered to shave seconds off your lap times while maintaining structural integrity.
  • MIPS C2 Brain Protection System: Rotational impact protection meets premium safety standards, reducing concussion risks during high-speed crashes or rough landings.
  • 24-Port Ventilation System: 10 front intake ports + 5 overhead channels + 7 rear exhaust ports create a microclimate airflow system that keeps you cool even during grueling descents or freestyle sessions.

Custom Fit for Maximum Comfort

  • 6 Size Configurations: Choose from 3 shell sizes (XS-XXL) paired with 3 EPS liner options for a precision fit tailored to your skull shape and riding style.
  • XT2® Quick-Dry Cheek Pads: Antimicrobial liners wick sweat away instantly while X-Static® headliner technology ensures a chafe-free ride—ideal for long-distance endurance events or repetitive training sessions.

Innovative Impact Absorption

The EPP Collarbone Impact System integrates a relief zone in the helmet’s lower center section to dissipate shoulder/collarbone collision forces during wipeouts—critical for riders navigating technical terrain or performing aerial tricks.


Essentials Included

  • Drawstring travel bag for easy transport
  • 3-year warranty backed by Troy Lee’s commitment to quality
