The life of your helmet
While visiting a Cycle Gear yesterday, I had an interesting conversation with the manager. Apparently, your helmet has a “shelf-life”. Meaning that, like bananas, you’ll eventually have to throw out your $700 Arai helmet because it “goes bad”. But, when? How long does a helmet last?
So, I did some research to find out what the life-cycle is like.
A Google search returns literally hundreds of results on internet forums and magazine websites, but I decided to go right to the source. Since I own a Shoei, I went to them directly.
First, find out what your manufacture date is:
“Where can I find the Production Date of my SHOEI helmet?
The Production Date is located on a sticker under the center pad of your helmet.” - source
According to the research I’ve done, 5 years is your shelf life. Now we ask the question: “Is that 5 years from manufacture date? Or 5 years from when I bought it?”
Surely, you can buy a helmet that’s been sitting on the shelf for 2 years, does this mean that you have to replace it 3 years after you buy it? This question was actually a hell of a lot harder to answer, and consequently not addressed on their website.
With a little more digging, I found this:
Helmet Replacement
Ultimately, the useful service life of a safety helmet is dependent on the intensity and frequency of its use. Helmet replacement is recommended even if only one of the under-mentioned points applies:
- The helmet was subjected to an impact.
- The comfort padding or the retention system has become loose due to heavy use or display signs of deterioration.
- The synthetic foam padding displays signs of heavy use and the helmet feels too loose. Test: with the retention system fastened, the helmet turns to the side when you gently shake your head.
- There are indentations in the EPS liner and/or white scratches can be seen on surfaces with black paint.
- Even if none of these is applied, we, SHOEI, recommend replacement in 5 years after it’s first purchased at retail.
So there we have it, right from the manufacturer’s mouth: Assuming the helmet is in new condition, you should replace it 5 years from purchase date. Either way, I’m due for a new helmet.
This past weekend I found a closeout sale on a REALLY cool Arai helmet that’s being phased out. The model is about 2 years old, and when the manager at CycleGear told me about the shelf-life, I got worried about it’s safety. Thanks to Google and good old-fashioned research skills, it looks like that Arai is in my near future after all.

How are you enjoying that new helmet? LOL
