Giro Shackleton

Don’t stop the ride when the temperatures plummet. The Shackleton helmet is ready for the cold with its cozy inner liner and separate neck roll with ear covers. The winter liner provides a variety of venting options, so you can customize the warmth of your helmet based on what the thermometer reads. As winter turns to spring and the temperatures rise, you can remove the liner and neck roll for a year-round riding solution. Other features include a removable, soft visor to shade your eyes, an integrated light clip at the back that allows you to snap your light to the helmet for enhanced visibility, and a reinforced vent that becomes a durable lock port so you can lock your helmet to the bike for convenience.
