Cookie G4 helmet

Cookie G4 Helmet Size S – Full Face Skydiving & Tunnel Helmet
The Cookie G4 in Size S is a full face helmet built for skydivers and tunnel flyers who need a snug, secure fit on smaller heads. Designed with input from world champion athletes, the G4 Size S fits head circumferences of approximately 54 to 55 cm and delivers the same wide field of view, low noise, and impact protection that make the G4 a go-to choice in freefall and indoor flight.

Fit, Visibility, and Impact Protection
The G4 Size S uses a lowered jaw line and refined internal shape to give you a panoramic field of view without the bulk of older full face helmets. The viewing area stays wide, so you can track other jumpers, camera targets, and tunnel walls with ease. The shell sits closer to your head than traditional designs, reducing drag and keeping the helmet stable in all orientations.

Protection meets the XPS 72-600 standard for skydiving and wind tunnel helmets. The helmet is tested for impacts at 5.47 m/s and includes a snag resistance test that other standards don’t require. The outer shell is high impact ABS, and the liner uses multi-impact EPP foam. These materials work together to absorb energy while keeping the helmet’s profile low. Cookie has also tested the G4 for penetration per EN966 and it passes with strong results.

The 2mm optically crafted polycarbonate visor is anti-fog and available in clear, tinted, orange mirror, and blue mirror. One visor fits all G4 sizes, so replacement and upgrades are simple. The flip-up mechanism is smooth with minimal maintenance. Adjustable ventilation lets you control airflow to reduce fogging and stay cool during long tunnel sessions or hot jump days.

Comfort, Customization, and Use
Inside, the G4 Size S seals well to lower wind noise and improve communication with other jumpers. The removable, washable liner is skin friendly and designed for quick drying. Audible altimeter pockets are easy to access, and the helmet includes a breathable mesh bag to help moisture escape after use.

Customization options are extensive. Choose from 13 matte colors like black, white, royal blue, and fluorescent pink, or opt for hydro-dipped Multicam and Multicam Black patterns. Engravable side plates let you add your name, team logo, or design. Note that adding external mounts may affect snag performance, so Cookie includes a trap door cutout in the EPP foam for cleaner installs.

The Cookie G4 Size S is certified for both skydiving and wind tunnel use. If you need a smaller fit and want a helmet that combines a wide view, low noise, and solid protection without excess bulk, the G4 delivers. Check with an authorized dealer to confirm fit and current lead times before ordering.
