The Diablo is designed for tweeners, not quite small enough for a kids helmet and not quite big enough for the adult models. Designed after the Macon/Brighton, the Diablo, uses Bern’s original visor shape and styling and scales it down a bit. Utilizing the EPS Thin Shell technology this lightweight burly construction is certified to protect you whether you’re on a bike or on the slopes. The winter model comes with a winter liner that will keep their head and ears warmer in those colder months at the local hill, but in the summer, can easily be transitioned to a bike helmet with a separate accessory summer liner.
