  • Remove the chin bar and carry it in your pack during long climbs; then lock it in place for an added boost of confidence when riding downhill on technical terrain
  • Float Fit technology lets you adjust the circumference and vertical positioning on your head for a perfect fit; revised shape inside and out enhances fit and comfort
  • While most helmets protect only against direct impact, MIPS technology reduces rotational forces when the helmet gets hit at an angle
  • Fused in-mold polycarbonate shell protects without being heavy
  • Overbrow Ventilation keeps air flowing so you don't overheat
  • X-Static padding absorbs sweat and dries fast to keep you cool; antimicrobial material inhibits the growth of odor-causing bacteria
  • GoggleGuide adjustable visor accommodates both goggles and glasses
  • Breakaway camera mount lets you attach your action camera to capture your adventure (camera not included)


To find your size, position a tape measure just above your ears and about 1" 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 Specs below.

I have a very small head at only 51 cm. Would the small be safe? I can't find a small enough helmet for cross country. I ride aggressively at high speeds.

Asked by: HollyA
As your head circumference is outside of the size range for a size small, we do not recommend this helmet for you.
