7iDP M2 Offers Lightweight Protection and Advanced Technology

When riding long distances, no one wants a heavy helmet weighing them down. The 7iDP M2 Bike Helmet not only offers an extremely lightweight protection option, but it also has advanced Conehead Technology to offer increased protection. 

7iDP's Conehead Technology utilizes dual density foams in impact-absorbing zones to help displace the force of a blow. This technology can help to divert injury or head trauma in the case of a crash. We love how soft plush cushioning of the M2 Bike Helmet and think it is comfortable enough to wear all day. 

The M2 has 19 vents to help keep the rider cool and a removable liner to allows for easy cleaning, so the M2 will last a long time. A one hand fit system also allows for easy adjustments, even during a ride.
