Giro Merit Roc Loc Trail Air Fit System
The Giro Merit Roc Loc Trail Air is Giro's patented helmet fit and stabilizing system. Genuine Giro replacement part. The Merit Roc Loc Trail Airreplacement hugs the back of your head and reduces the tendency of your helmet to shift forwards or backward. Unlike most systems, the Giro Merit Roc Loc Trail 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 Merit Roc Loc Trail Air fit system is the world's finest. It features separate tensioning and positioning adjustments plus a soft rubber over-molded fit belt that hugs your head in luxury.

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