Rock the speed and other challenges of downhill with the ASTM downhill-certified full-face design and removable chin bar of the streamlined Giro Switchblade MIPS bike helmet.

  • Features

    • Optimized for the descent, this helmet is certified to CPSC, EN-1078 and ASTM-1952-DH, both with and without the chin bar
    • While most helmets protect only against direct impact, MIPS technology reduces rotational forces when the helmet gets hit at an angle
    • Chin bar detached easily—just push the buttons underneath, rotate up and remove; it's also just as easy to reinstall
    • When the chin bar comes off, Wind Tunnel cheek pad ventilation adds even more cooling power for your climb
    • Roc Loc® Air DH fit system includes a bumper around the dial to prevent accidental adjustments if your helmet comes in contact with your backpack or neck brace
    • Full-cut style offers an aggressive look
    • In-mold polycarbonate shell with 27 vents, EPS liner and CoolMax® polyester padding


    To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
