Ruby Helmets Castel Helmet | St. Roc

Availability: Out of stock

Castel (Full Face)

Important information regarding size:

The full face helmets are very tight when new. However, the padding will take the shape of your head with time. If your helmet already fits very tight with your usual size, we recommend taking one size larger for full face helmets than the size you chose for the open face helmets.

Be it on a Harley-Davidson or Triumph motorcycles, your full face helmet will always appear as the perfect fit for the ride.
