Where to look for the helmet's manufacture date

The year your motorcycle helmet was made is printed on a label inside the helmet, usually on the foam padding or the inner lining. Look for a date code that shows the month and year of manufacture — it typically appears as two digits for the month followed by two digits for the year, like "03/18" for March 2018. Some helmets use a longer format with the full date spelled out.

The label is almost always on the back or side of the interior, near where the padding meets the shell. You may need to tilt the helmet or use a flashlight to read it clearly, especially if the interior is dark. If you cannot find a date on the main interior label, check the chin strap attachment points or any secondary labels sewn into the helmet.

Key Takeaways

  • The manufacture date is printed on a label inside the helmet, usually on the foam padding or lining near the back or sides.
  • The date typically appears as two digits for month and two for year, such as "03/18" for March 2018.
  • You may need a flashlight to read the date clearly, especially in darker helmet interiors.
  • Most helmet manufacturers place this label in the same general location, though the exact spot varies by brand and model.
  • If the label is worn or illegible, contact the helmet manufacturer with the model number to confirm the age.

Why manufacturers put dates on helmets

Helmet manufacturers include manufacture dates because the materials inside — foam, padding, and adhesives — break down over time, even if the helmet is never worn. Ultraviolet light, temperature changes, and humidity all degrade these materials, which means an old helmet may not protect your head as well as a new one, even if it looks fine on the outside.

Most safety organizations recommend replacing a helmet every five to ten years from the date of manufacture, depending on how often you wear it and how you store it. A helmet stored in a hot garage or exposed to direct sunlight will age faster than one kept in a cool, dry place. The manufacture date lets you track how old your helmet actually is, not just how long you have owned it.

What to do if you cannot find the date

If the interior label is worn, faded, or missing entirely, look for the helmet's model number or brand name on the exterior or interior. You can then contact the manufacturer directly with this information — most helmet companies keep production records and can tell you approximately when that model was made.

You can also check the original receipt or packaging if you still have it, as the purchase date gives you a starting point. Keep in mind that a helmet may have been in a store's inventory for months before you bought it, so the purchase date is not the same as the manufacture date. If you cannot determine the age and the helmet shows visible damage, cracks, or dents, it is safer to replace it rather than guess.

Reading different date formats across brands

Not all helmet manufacturers use the same date format. Some use month/year (03/18), others use year/month (18/03), and a few spell out the month entirely (March 2018). DOT-certified helmets sold in the United States must include a DOT label, which sometimes includes the date, though not always in an obvious place.

Snell-certified helmets often have a more detailed label that includes the certification year and sometimes the manufacture date separately. If you own a helmet from an international brand, the date may be in a different format or language. When in doubt, take a photo of the label and send it to the manufacturer — they can confirm the date even if the format is unclear to you.

How helmet age affects safety

A helmet that is ten years old may look perfectly fine but have foam that no longer absorbs impact as effectively as it did when new. The outer shell can also become brittle over time, especially if exposed to sunlight or extreme temperatures. This does not mean an older helmet is useless, but it does mean the protection it offers has declined.

If you ride frequently, replacing your helmet every five years is a reasonable guideline. If you ride occasionally and store your helmet indoors away from heat and sunlight, you may be able to extend that to seven or eight years. The key is checking the manufacture date and being honest about how much sun and heat exposure the helmet has had.

Storing your helmet to slow aging

Once you know how old your helmet is, you can take steps to slow further deterioration. Keep it in a cool, dry place away from direct sunlight — a closet or garage shelf is better than a sunny windowsill or a hot attic. Avoid storing it in a hot car or a damp basement, both of which speed up material breakdown.

Do not hang your helmet on a hook by the chin strap for long periods, as this can stretch the strap and put stress on the attachment points. Instead, store it upright or on its side on a shelf. If you use your helmet regularly, the sweat and oils from your head will also age the interior padding, so cleaning the interior occasionally with a dry cloth helps preserve it longer.

Frequently Asked Questions

What does the date on a helmet actually mean?

The date shows when the helmet was manufactured at the factory, not when it was sold or when you bought it. A helmet made in 2018 but purchased in 2022 is still four years old from the manufacture date, even though you just got it.

Is a five-year-old helmet still safe to wear?

A five-year-old helmet that has been stored properly and not crashed is generally still safe, though the foam may have lost some effectiveness. If it has been exposed to heat or sunlight, or if you ride frequently, replacing it sooner is a better choice.

Can I tell a helmet's age just by looking at it?

No. A helmet can look brand new but be ten years old if it was never worn and stored well. The only reliable way to know is to read the manufacture date on the interior label.

What if the date label is completely illegible?

Contact the helmet manufacturer with the model number or brand name. They can often tell you the approximate manufacture date based on production records. If you cannot reach them or determine the age, replacing the helmet is the safest option.

Does a helmet expire on a specific date?

Helmets do not have a hard expiration date, but most safety organizations recommend replacement every five to ten years depending on use and storage. Check your helmet's manufacture date and replace it if it is approaching ten years old or if it has been in a hot or sunny environment.
