Helmet Safety Standards Explained

The standards shown on the helmet label tell you which types of riding accident scenarios your helmet has been tested for.

What is EN1384:2003?

The latest European standard for equestrian helmets. Tests for impact, penetration, retention, and stability.

What is ASTM F1163-23?

The American safety standard for equestrian helmets. Certification is managed by SEI.

What is ISO 9001?

A company accreditation that is the world’s leading standard for quality management systems. It helps organisations to consistently deliver products and services that meet customer legal requirements while driving continuous improvement.

What is a CE Mark?

All helmets sold in Europe must legally carry the CE mark, which confirms conformity with EU regulations. It is not a performance test, but a mandatory compliance mark.

What is BSI (British Standards Institution)?

Independent body that tests helmets. When a helmet has the BSI Kitemark, it means every production batch is checked and audited.

What is a Kitemark ?

The BSI Kitemark is a trusted UK quality mark from the British Standards Institution. When you see the Kitemark on a helmet, it means:

  •  - The helmet has been tested to the relevant safety standard (e.g. EN 1384:2023).

  •  - Every production batch is also independently checked and audited by BSI.

  •  - It’s proof of ongoing, consistent safety and quality, not just a one-time test

What is SEI (Safety Equipment Institute)?

US organisation that certifies helmets to the ASTM standard. The SEI Mark comes from the Safety Equipment Institute in the USA. On a helmet, it means:

 - The helmet has been independently tested and certified to the ASTM F1163 equestrian standard.

 - Factories and processes are also subject to regular audits.

 - It’s the US equivalent of the Kitemark, showing the helmet is compliant and safe for the American market.

How do I adjust the fit of my LeMieux helmet?

Check out our fitting videos HERE

 

Use the 360° Wrap Fit control wheel at the back. Turn clockwise to tighten, counterclockwise to loosen. Add the 5mm or 10mm padded ‘donuts’ inside the helmet to fine-tune the fit.

When should I replace my LeMieux helmet?

Replace your helmet every 3 to 5 years, or if it has been involved in an impact, even if no visible damage is seen. Replace the helmet if it no longer fits correctly.

How does the ventilation work?

Our helmets use six large crown vents to reduce heat stress. They’re engineered to maximise airflow while still meeting all penetration and impact requirements, providing cooling without compromising safety

How should I care for my helmet?

Check out our care guide video HERE

 

Your helmet should be cared for like your own head. Each comes with a protective bag, and using a LeMieux Hat Box helps prevent knocks and scratches. The finishes use automotive-grade, UV- and abrasion-tested coatings for long-term durability.

 

The central padding is removable and can be machine washed at 30°C.

How to return a helmet?

We want you to be fully happy with the fit. Unworn helmets can be returned or exchanged as long as the safety tag is still attached. Try it on carefully (ideally with a LeMieux preferred retailer), and if it’s not right, return it in the original packaging with proper padding. For safety and hygiene reasons, helmets used for riding can’t be accepted. Professional in-store fitting is always the best option.
