Giro Helmet Air Attack Roc Loc Air
The Roc Loc Air is Giro's patented helmet fit and stabilizing system. The genuine Giro Roc Loc Air replacement part hugs the back of your head and reduces the tendency of your helmet to shift forward or backward. Unlike most systems, the Giro Roc Loc Air design provides adjustable tension that is independent of the helmet straps. What this means is that you don't have to over-tighten the straps to get a snug, comfortable fit.
The Giro Roc Loc Air fit system is the world's finest.

NOTE: Roc Loc systems are designed to fit ONLY the original helmet. You can not retrofit a helmet with a different model RocLoc.
