Expired – aging helmets and the quiet ways things wear out

Written by: Robert Eversole

Oh my. My helmet is expired.

October 2016. Ruh roh.

That helmet has seen some country with me. Arizona deserts. Washington high country and a lot of wilderness miles with horses and mules in between. It’s been shoved into tack rooms, bounced around truck cabs, dropped in parking lots, and baked in summer heat that probably wasn’t doing it any favors. Through all of it, the helmet quietly did its job while I rarely gave it much thought. My noggin remains largely intact, which is more than can be said for some other body parts over the years. But like all things that live a hard-working life around horses, its time has apparently come.

What surprised me wasn’t the idea that helmets need to be replaced after a crash. Most riders understand that part. If a helmet takes a hard hit, replace it. Simple enough. What caught me off guard was learning how much the materials themselves slowly age even when nothing dramatic happens. Most riding helmets use EPS foam, a crushable material designed to absorb energy before your skull does. But like many materials exposed to time, sweat, sunlight, and heat cycles, it slowly changes. The foam becomes more brittle. Adhesives weaken. The shell slowly degrades from years of UV exposure and temperature swings. None of this happens overnight, and that’s what makes it easy to miss.

The sneaky part is that an expired helmet can still look fine. Mine certainly does. Other than a few scuffs, there aren’t any cracks or obvious damage. Nothing about it says “retirement home.” If I hadn’t glanced at the date, I probably would have kept using it without another thought. That’s the uncomfortable thing about aging, both for safety equipment and us. Neither usually fail in some dramatic moment. They just quietly become less effective over time. Most manufacturers, including Troxel and Charles Owen, recommend replacement somewhere around the five-year mark depending on use and storage conditions. Organizations like the Snell Memorial Foundation say much the same thing. I’ve apparently been treating those recommendations more like friendly suggestions than actual guidelines. Kind of like the interstate speed limit.

Part of the reason this one stuck around so long is that it fit well. Anyone who wears helmets knows how rare that can be. A good helmet disappears once you put it on, which is exactly what you want from something sitting on your head for hours at a time. Replacing it means starting over with that awkward phase where a new helmet feels slightly wrong. Too tight here. Too loose there. One pinches your forehead while another feels like a mushroom balanced on top of your skull. Finding the right fit takes a minute, and once you finally have it, it’s hard to let go.

There’s also something sentimental about old gear. Sometimes equipment stops feeling like an object and starts feeling more like a companion. Saddles get that way. A favorite knife. A coffee pot blackened from campfires. They become tied to memories and miles. That helmet has been with me through enough rides and wilderness trips that tossing it in the garbage feels disrespectful. I’m tempted to turn it into a flower planter.

The older I get, though, the more I believe prevention rarely gets the credit it deserves. Nobody gathers around camp to celebrate the wreck that never happened. Horse people, myself included, can be funny about risk. We’ll replace a saddle pad because the color faded while trusting aged safety gear with our brains. Good helmets aren’t cheap, and replacing something that still “looks fine” feels wasteful. But the fact is; helmets are consumable safety gear. The materials slowly age and lose effectiveness over time.

That’s not a conspiracy by helmet companies. It’s just materials science.

If this were only about comfort or appearance, I’d probably run mine until it fell apart. But when it comes to my head, I lean more conservative these days. I’d rather replace a helmet a bit early than discover too late that it wasn’t as protective as I thought it was.

So now I’m helmet shopping again, which feels a little like dating after a long marriage. Out in the shop sits a comfortable helmet from October 2016 that probably deserves a small retirement ceremony.

When I look for a replacement, I keep it simple. First, is it certified as an equestrian helmet? Look for the SEI certification sticker. Second, is it comfortable? An uncomfortable helmet usually becomes a forgotten helmet. Different manufacturers fit differently, so try on several and wear them for a few minutes. One will usually stand out from the rest.

Might be worth checking the born-on date inside yours the next time you ride.
