HRX Auto Racing Suits
FIA-Homologated — Sizing Guide & How to Measure Yourself
HRX is an Italian bespoke motorsport brand offering both standard-size and made-to-measure FIA-homologated auto racing suits. Whether you’re competing in circuit racing, rally, or track days, a precise fit is critical for both safety and performance behind the wheel. This page walks you through everything you need before placing your order.
HRX auto racing suits are available with FIA 8856-2018 and FIA 8856-2000 homologation. Check the specific product listing for the homologation standard applicable to each suit model before purchasing for competition use.
Step 1 — Download the Size Chart
Start by downloading the official HRX auto racing suit size chart. It covers all categories:
- Adult – Man (sizes 46–64, S through 2XL)
- Adult – Woman (sizes 38–56, XS through XL)
- Young (sizes 38–44)
- Child (120–150 — ages 6–13)
All measurements are circumferences expressed in centimeters (cm). Child sizing also includes thigh and crotch measurements.

Step 2 — Take Your Measurements
Follow these rules for accurate measurements:
- Use a soft measuring tape only.
- Measure wearing underwear only — never over clothing.
- Place the tape at belly button level as a reference for waist.
- Do not add extra cm — HRX builds in the necessary ease for a race-ready fit.
- Have someone assist you for the most accurate results.
- If you plan to wear a rib protector or back protector under the suit, measure your chest while wearing the device.
Key Measurements for Standard Sizing
| Measurement | How to Take It |
|---|---|
| Chest | Largest part of the chest, under the armpits |
| Waist | Belly button level |
| Pelvis / Hips | Largest point of the hips, ~22–23 cm from waist |
| Thigh (Child only) | Largest circumference of the thigh |
| Crotch (Child only) | Circumference measurement — see size chart |
| Weight | In kilograms (kg) |
| Height | In centimeters (cm) |
Step 3 — Standard or Made to Measure?
Once you have your measurements, compare them against the size chart:
- If your measurements match a standard size — select that size when ordering. You’re good to go.
- If your measurements fall between sizes or you have a non-standard build — a bespoke made-to-measure suit is the right choice for a precise, competition-ready fit.
A fully completed HRX Measurement Form is required before your order can go into production. We will contact you after your order is placed to collect the form. Production typically takes 4–6 weeks.

Are HRX racing suits FIA homologated?
Yes. HRX auto racing suits are available with FIA 8856-2018 and FIA 8856-2000 homologation, meeting the safety standards required for circuit racing, rally, and other FIA-sanctioned motorsport disciplines. Always verify the homologation standard on the specific product listing before purchasing for competition.
What is the difference between FIA 8856-2018 and FIA 8856-2000?
FIA 8856-2018 is the current and more stringent standard, offering improved thermal protection and comfort. FIA 8856-2000 is the older standard, still accepted in many series. Check your specific championship’s regulations to confirm which standard is required before ordering.
What is the difference between a standard and a made-to-measure HRX racing suit?
A standard HRX racing suit is produced in fixed sizes based on average body proportions. A bespoke made-to-measure suit is crafted to your exact body measurements across 16 measurement points, ensuring a precise, competition-ready fit for drivers with non-standard proportions or specific customization needs.
How long does an HRX made-to-measure racing suit take to produce?
HRX bespoke made-to-measure racing suits typically take 4 to 6 weeks from the time your completed measurement form is received and approved. Plan ahead if you have an upcoming race or event.
How do I submit my measurements for a made-to-measure HRX racing suit?
After placing your order, our team will contact you to collect your completed HRX Measurement Form. The form must be fully filled out with all 16 body measurements. You can download the form from this page to prepare in advance. Incomplete forms will delay production.
Can I return or exchange a made-to-measure HRX racing suit?
Made-to-measure suits are custom-produced to your specific measurements and cannot be returned or exchanged unless there is a manufacturing defect. HRX does not accept responsibility for errors resulting from incorrect measurements provided by the customer. Please measure carefully and double-check before submitting your form.
What fitting options are available for HRX made-to-measure racing suits?
When ordering a bespoke HRX racing suit, you can specify your preferred fitting style: Close (tight, performance-oriented), Standard (balanced comfort and fit), or Loose (more relaxed). You can also customize pockets, belt, and leg bottom style on the measurement form.
Do HRX racing suits come in youth and children’s sizes?
Yes. HRX offers a Young category (sizes 38–44) for junior drivers, and dedicated Child sizing (120–150) for ages 6–13. Child suits require additional measurements including thigh and crotch circumference. A made-to-measure option is available for young drivers with non-standard proportions.
