- A lot quieter as it seals better in all areas and the exterior shape is sleek and smooth by design

DETAILS ON THE G4 LINER
The adjustment of the neck skirt is the same as the G3, although the adjustment end is located in an easier place to facilitate this.
G4 VENTILATION CONTROL
The internal EPP foam has been styled to create channels within the helmet to provide ventilation. The top padding also has breathable material to allow the hot air to be drawn into these channels.
The chin bar actuators can control the airflow to your mouth area as well as direct to the inner surface of the visor.
Two rear ventilation ports allow the evacuation of this hot air from within the helmet.
CERTIFIED G4 VISOR
One visor fits all the G4 helmet sizes. Visors have an anti-fog inside and anti-scratch outside. Cookie offers a tinted, blue mirrored and orange mirrored visor options. G4 visor is tested for its optical qualities, and as such it has been certified and carries a CE mark.
The visor is very simple to remove. Undo the two side plates screws on both side of the visor. Remove these plates and slide the visor forward. Tinted and mirrored visors are certified to Category 2 against ISO 12312-1:2013.

FITTING A CAMERA TO G4 HELMET
The G4 Helmet is certified to a Skydiving and Wind Tunnel Helmet Standard. To achieve this standard, helmets must pass Impact and Snag Resistance testing. While G3 Roller mount base is a good fit against the top surface of the G4, it was not tested according to the XP S 72-600 Standard. Cookie believes that having a Roller Mount fitted to the G4 helmet would forgo the Snag Test in this standard. It is up to the user to decide whether to mount a camera to our G4 helmet knowing that by doing so, it could affect the way the helmet performs when tested to the XP S 72-600 Standard.
