Giro's Sutton is a low-profile design loaded up with clever features to help urban riders and commuters get more out of their ride, and now it's available with the Roc Loc City fit system. This fit system has three positions of vertical adjustability, and a comfortable, rubberized dial to adjust tension. It is made of a flexible and durable material to avoid damage while being locked up. The Sutton also features a tough outer shell and a soft visor. An integrated light clip at the back allows you to snap your light to the helmet for enhanced visibility, and a reinforced vent becomes a durable lock port so you can lock your helmet to the bike for convenience.
