In Form™ Fit System – The In Form™ Fit system makes it easy to dial in a custom fit in seconds – even with gloves on. An ergo- friendly dial at the base of the helmet provides up to 6cm of fit/feel adjustment and enhanced stability, and the system also offers vertical tuning of the helmet’s fore/aft position to match different goggles and head shapes.
