We knew the demand for a high performance helmet with the SevenTechnology liner
that adjusts down for smaller heads was big.  Understated.   The SPRfit (Swiss Precision
Ratchet that is) answers the bell with attitude.  Check out the fellas at Cornell (you ever heard of it?)
or their wicked smahht rivals in Beantown to see the R in action.  All the smart kids are doing it.  
Mask available in Chromanium  
One size fits most.
