The most beautiful and technologically advanced road cycling helmet Giro has ever made comes fully equipped with ground-breaking ventilation, unparalleled style, and a brand new retention system for an amazing level of comfort, stability, adjustability and weight savings.
  • In-Mold construction reinforces the area around the vents and ribs, creating a one-piece exoskeleton, which allows the helmet to be lighter, more durable and better ventilated than traditional designs
  • Roll Cage is a light-yet-tough web of reinforcement, invisibility molded inside the helmet's EPS foam liner for maximum impact protection, strength and integrity
  • In-Mold Composite Sub Frame is tuned to deliver incredible structural support, impact dispersion and resistance to penetration (and it's the secret to this helmet's ability to offer great big vents without compromising protective capability)
  • 21 massive Wind Tunnel vents with internal channels thrust 15% more cool, fresh air over and around your head while forcing heat and stale air out
  • Impact absorbing, antimicrobial X-Static padding offers unprecedented comfort and manages moisture
  • Quite possibly the best-fitting retention system you've ever experienced, the Roc Loc 5 easily adjusts both fit tension and vertical position with a single hand, plus it's 40% lighter than its popular predecessor, Roc Loc 4
  • Certified CPSC
  • Suggested Use: Road, Race, Triathlon, MTB, X-Country Race, Cyclocross, Touring
