ASTM F1163 and Snell E2021 are separate standards with different certification programs. Check the label on the exact helmet, current competition rules and official lists; no helmet can prevent every injury.
ASTM F1163 and Snell E2021 are different equestrian helmet standards. The label on the actual helmet and the current competition rulebook matter more than a store filter. Certification to one standard does not automatically mean certification to another.
Compare what to verify
| Check | ASTM F1163 | Snell E2021 |
|---|---|---|
| Standard | ASTM equestrian helmet standard; current edition is F1163-23 | Snell equestrian helmet standard E2021 |
| Verification | Check the helmet’s certification label and the SEI listing | Check the helmet label and Snell’s E2021 certified list |
| Competition use | Confirm the current discipline and event rule | Confirm the current discipline and event rule |
Do not treat a helmet sold as “ASTM” or “Snell-style” as certified without the applicable label and official listing. A product can carry multiple certifications, but verify each one independently.
USEF publishes current rulebooks, and rules can differ by discipline and event. FEI rules also change; check the applicable body’s current equipment rules before competing. No helmet can protect against every foreseeable injury. Fit, secure harness, replacement after an impact and maker guidance remain important.

No. Competition requirements vary and change. Check the current rulebook for the discipline and event.
Does ASTM/SEI mean the helmet is Snell certified too?
No. Each standard is a separate certification. Check the actual labels and certification listings for the helmet model.
Can a certified helmet prevent all head injuries?
No. US Equestrian cautions that serious injury or death can occur even when protective headgear is worn.
