The lightweight Crane Commuter is based on the award-winning Crane, where the tough outer shell and inner liner are made of two different densities. The harder outer shell absorbs high impact energy, while the inner EPS liner provides protection from lower impact energy. Together, the two different densities provide optimal protection in the event of an impact. The Crane Commuter features a magnetic closure for easy, one-handed operation and a special size adjustment system for a perfect fit and secure hold.
