It All Comes Down to This:
In the end, what are your comfort and confidence are worth to you?
Can you really put a "price" on them? An Arai helmet isn't inexpensive. It isn't made to be.
And when you wear one, it isn't made to feel good for just an hour or two. It's made to feel good all day, every day - and to keep feeling good for years, long after cheap helmets have become loose and shabby (and probably had to be replaced more than once).
You can't always see the reasons why an Arai feels better, but they're there: lower weight from aerospace fiberglass-based construction; a lower center of gravity for better balance and less strain; softer single-piece multiple-density liners (whose technology still hasn't been able to be copied in almost 20 years). Ventilation systems that work in the real world, not just in drawings. A helmet with no "minor" parts. And the result is major: you just feel good. You want to keep riding.
That's why we build our helmets the way we do. Because it's not about what you pay, it's about what you get.
You could go through a bunch of cheaper helmets in the lifespan of just a single 5-year-warranty Arai - and wind up spending more in the long run. Worse, you'd miss out on Arai's legendary comfort, fit, features, and feeling of confidence along the way. A helmet is something you're going to spend too much time and too many miles in to not ensure that every bit of it is a pleasure. So compromise somewhere else.
Maybe that's why someone once said that when you consider everything that goes into an Arai helmet, the price almost sounds like a bargain.
Few of us can afford to own the very best of most things. But with an Arai helmet, you truly can own the very best of something.
