Impact OS20 Helmets in This Collection
- Impact Carbon Fiber OS20 RACE Offset Air SA2025 Helmet Wired OFFROAD: carbon-fibre OS20 RACE with a left-positioned 20° offset air inlet, three air channels and a wired Rugged Radios helmet kit.
- Impact Carbon Air Draft OS20 Helmet SA2025: carbon-fibre OS20 with 20° offset fresh-air inlet, triple-channel airflow and HNR-ready back plate; listed as unwired, with compatible communication kits available separately.
The offset air position can improve clearance around a roll cage, roof bar or low cockpit. Airflow across the visor can help manage fogging and dust; check the exact hose and clean-air setup for your vehicle.
Wired, Unwired and Forced-Air Choices
The wired OS20 RACE listing includes a Rugged Radios helmet kit. The Carbon Air Draft OS20 is listed as unwired, so a compatible kit is needed for helmet-to-intercom audio. Check connector and intercom fit before ordering. The collection also includes a wired Simpson Carbon Desert Devil, an MRC Opposition helmet with headset choices, an Impact Velcro RACE dust skirt, visor shields and Racing Optics tear-offs for specified Impact and Simpson models.
SA2025 and Motorsport Event Requirements
The two Impact OS20 helmet listings identify them as Snell SA2025. SA2025 is the current Snell motorsport helmet standard and is accepted by MotorSport NZ and Motorsport Australia. Confirm each supplied helmet’s physical label, condition and the rules for your exact discipline and class, including forced-air, communications and FHR requirements. Acceptance of the standard does not make every helmet configuration suitable for every class.
Fit, Sizing and Head-and-Neck Restraint Guidance
Helmet fit is model-specific. Use the size chart and measuring instructions on the product page and contact us if between sizes. An HNR-ready back plate does not by itself establish compatibility with every FHR device: check the helmet, posts, restraint, seat and vehicle setup.

Frequently Asked Questions
Which Impact helmets are in this collection?
Impact Carbon Fiber OS20 RACE Offset Air SA2025 Helmet Wired OFFROAD and Impact Carbon Air Draft OS20 Helmet SA2025, plus related helmets and accessories.
What is the Impact OS20 forced-air system?
An offset air inlet and three air channels direct fresh air through the helmet, with a layout that can help clear cage bars and low cockpit structures. Check the hose fit.
Are the Impact OS20 helmets SA2025 certified?
The two OS20 listings specify Snell SA2025; verify the physical labels. SA2025 is the current Snell motorsport standard accepted by MotorSport NZ and Motorsport Australia. Check condition and your class-specific helmet and FHR requirements.
Is the Impact OS20 helmet wired for communications?
OS20 RACE includes a wired Rugged Radios kit; Carbon Air Draft OS20 is listed as unwired and may need a compatible communications kit separately.
Are these helmets suitable for off-road and rally racing?
They are listed for those applications. Check the exact helmet, vehicle and class rules, plus air-hose and communications fit.
How do I choose the correct helmet size?
Use the size chart and measuring instructions for the exact model. The fit should be firm without unwanted movement; ask us if between sizes.
Can I use an Impact helmet with a HANS or FHR device?
Check the complete helmet, approved posts, restraint, seat and installation setup; an HNR-ready back plate alone is not a universal fit guarantee.
Can I add radio communications to the non-wired OS20?
Compatible kits are listed separately. Confirm helmet-kit, connector and intercom fit before ordering.
Does the collection include replacement and cleaning accessories?
Yes, including dust skirts, visor shields and Racing Optics tear-offs. Check model-specific fit.
Are Impact helmets approved for MotorSport NZ or Motorsport Australia?
The Snell SA2025 standard is accepted by both. The exact helmet’s physical label, condition and configuration must also meet the requirements of your class and event; ask the organiser about your specific setup.
