Impact OS20 helmets in this collection
- Impact Carbon Fiber OS20 RACE Offset Air SA2025 Helmet Wired OFFROAD: a carbon-fibre OS20 RACE helmet 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: a carbon-fibre OS20 helmet with a 20° offset fresh-air inlet, triple-channel airflow and an HNR-ready back plate. This model is listed as not wired, with compatible communication kits available separately.
The offset air layout is useful where a centred air inlet could interfere with a roll cage, roof bar or low cockpit. The OS20 product information also describes airflow directed across the visor to help manage fogging and dust while preserving communication performance.
Wired, non-wired and forced-air choices
Check the individual product page carefully before ordering. The wired OS20 model includes a Rugged Radios helmet kit, while the Carbon Air Draft OS20 listing states that it is not wired and needs a compatible communication kit if you want helmet-to-intercom audio. Connector and intercom arrangements vary, so confirm compatibility with your existing radio system before purchase.
This collection also includes related off-road helmet options and equipment, including a wired Simpson Carbon Desert Devil helmet, an MRC Opposition helmet with headset options, an Impact Velcro RACE helmet dust skirt, Impact visor shields and Racing Optics tear-offs for Impact and Simpson helmet models.
SA2025 and motorsport event requirements
The two Impact OS20 helmet listings in this collection identify the helmets as Snell SA2025. That does not automatically guarantee eligibility for every event, class or category. Motorsport New Zealand, Motorsport Australia, individual series and scrutineers can apply different standards, age limits and equipment requirements. Confirm the current rule set with your event organiser or scrutineer before purchasing or racing.
Fit, sizing and head-and-neck restraint guidance
Helmet sizing is product-specific. Use the size table and measuring instructions on the individual product page, and contact Harris Race Radios before ordering if you are between sizes or unsure about the fit. Some OS20 product information identifies an HNR-ready back plate, but HANS or FHR compatibility should be confirmed for the complete helmet, restraint, seat and vehicle setup rather than assumed across the entire collection.
Why buy Impact helmet equipment from Harris Race Radios?
Harris Race Radios supports motorsport competitors across New Zealand and Australia with helmet, communications and forced-air selection advice. Rex Harris is a qualified Radio Telecommunications Engineer and Approved Radio Certifier for NZ RSM and Australian ACMA, with motorsport radio experience since 1975. Aaron Harris is an active racing driver and race engineer, and an MSNZ Licence Examiner. Their roles are kept separate: radio and communications certification advice is not the same as certifying a helmet or approving a vehicle for competition.
Frequently asked questions
Which Impact helmets are in this collection?
The collection includes Impact Carbon Fiber OS20 RACE Offset Air SA2025 Helmet Wired OFFROAD and Impact Carbon Air Draft OS20 Helmet SA2025, together with related off-road helmet options and Impact helmet accessories.
What is the Impact OS20 forced-air system?
The OS20 system uses an offset air inlet and three air channels to direct fresh air through the helmet. The offset position can help create clearance around roll-cage bars, roof structures and low cockpits.
Are the Impact OS20 helmets SA2025 certified?
The two Impact OS20 product listings in this collection identify the helmets as Snell SA2025. Always confirm whether that standard is accepted for your specific event, class and category before purchasing.
Is the Impact OS20 helmet wired for communications?
The Impact Carbon Fiber OS20 RACE listing includes a wired Rugged Radios helmet kit. The Impact Carbon Air Draft OS20 listing states that it is not wired, so a compatible communication kit may be required separately.
Are these helmets suitable for off-road and rally racing?
The Impact OS20 product information identifies off-road, rally and other motorsport applications. Final eligibility depends on your vehicle, class, event and current governing-body requirements.
How do I choose the correct helmet size?
Use the measuring instructions and size table on the individual product page. A racing helmet should fit firmly without movement. Contact Harris Race Radios if you need help comparing your measurement with a specific model.
Can I use an Impact helmet with a HANS or FHR device?
Some OS20 information identifies an HNR-ready back plate, but compatibility depends on the complete helmet, restraint, seat and installation setup. Confirm the specific combination before purchase.
Can I add radio communications to the non-wired OS20?
The non-wired Carbon Air Draft OS20 listing states that communication kits are available separately. Confirm the connector, helmet kit and intercom fitment before ordering.
Does the collection include replacement and cleaning accessories?
Yes. Related items include an Impact helmet dust skirt, replacement Impact visor shields and Racing Optics tear-offs for listed Impact and Simpson helmet models. Check the product compatibility information for your helmet.
Are Impact helmets approved for Motorsport New Zealand or Motorsport Australia?
Approval depends on the helmet standard, event, class, age requirements and current rules of the controlling body. Confirm the current requirements with Motorsport New Zealand, Motorsport Australia or your event organiser before racing.
