HELMET DAMPENING FIT SYSTEM
A fit system for a helmet can include an adjuster including a width adjustment track, and first and second pods moveably coupled to the width adjustment track with a first and second support arm, the second pod comprising a lateral offset from the first pod. The fit system can further include a dial moveably coupled to the adjustor, such that movement of the dial changes a size of the lateral offset between the first pod and the second pod. The fit system can further include a hanger flexibly coupled to both the first pod and the second pod and adapted to allow for adjustment of the lateral offset between the first pod and the second pod. The hanger can further be adapted to allow for movement of the first pod and the second pod in a direction substantially perpendicular to the lateral offset without movement of the dial.
