We took everything we've learned from 30 years of helmet development and challenged ourselves to achieve the lowest-profile, deepest-fitting, most comfortable helmet in the world. 

• Patent-Pending HIDDEN-HINGE Technology provides just the right amount of auto-flexing adjustment deep inside
• The Back Fit LUXE-LOCK Liners are a revelation with 3 densities of precision-shaped foam wrapped in sweat-wicking fabric to cradle the occipital region at the base of your skull. Once you experience it, there's no going back
• Advanced FIT KIT with 17 Liners and Shims for customization to your unique head shape
• Classic Shape, Deepest Fit, and Lowest Profile in 4 sizes each with unique ABS and EPS Shell for the closest fit to your head
• Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older, ASTM F1447 Standard Specification for Helmets Used in Recreational Bicycling or Roller Skating, and ASTM F1492 Standard Specification for Helmets Used in Skateboarding and Trick Roller Skating.
