Do you ride bikes? I mean more than one? How many bikes are in your garage? If you’re like us, it’s more than two and less than the number your significant other will leave you over. Thing is, different bikes call for different accessories. What if there was a helmet that crossed over all styles, all seasons? There is… The Bollé One helmet covers every ride from road to trail to triathlon and from summer heat to winter cold.

Normally, you’d need at least two helmets – one for road and one for trail.  If you race triathlons, you may grab an aero helmet.  That’s somewhere between $300-$500 if you buy nice lids.  Add in a liner for cold days and you’re up another $20-30.  Ouch, my wallet hurts.

To replace all these helmets, the Bollé One helmet comes in a very full box. Each helmet comes with the helmet itself, a visor, vent-cover panels, a full liner, and a tail light. What the heck do you do with all these pieces? We’ll let some pictures tell the story…

There’s really nothing the One helmet can’t do. But, the question is, does it to everything well? The answer is: mostly. The helmet itself is vented well with 31 overall vents and has your normal fit adjustments. We’ve always though that the sign of a good helmet fit is when it disappears on your head. The One does.

Construction is good.  Seams between in-molded plastic and foam are uniform and solid.  We were actually surprised at how compact the helmet is.

So, how does it fit? The Bollé One features the now-standard ratcheting mechanism at the back of the head to adjust sizing. It works just fine. We found the helmet to have a slightly oval fit that can’t really be adjusted. So, if you have a rounder head than average, you may need to look elsewhere for a lid.

One of the most innovative features of the Bollé One is the full liner. With most helmets, you slip a skull cap underneath for cooler weather, changing the fit. With the One, you pull the summer pads, insert the full liner, and you have a warm helmet that fits exactly the same with no adjustments.

You can also attach things to the outside of the helmet to add features. For extra chilly days, or aero needs, add the vent-cover panels. They block cold air from getting in and make you more aero at the same time. Dual purpose! The vent covers come in three colors – red, white, and blue.  Or, toss the taillight on for evenings. It’s not the brightest or easiest to use, but more lights are better than fewer.  The on-off switch is finicky.  You need a hex or a pen or something to pop out the panel that covers where the light installs.

Unfortunately, Bolle’s visor is useless. Some of you may not ride with a visor. We like them and wish that Bollé did a better job with the design. It’s floppy, doesn’t extend out enough to block any sun, but does manage to block a decent portion of the main air vent.  We also like shoving our shades into our helmet vents. Bolle’s vent placement make that tough.  Maybe we’re doing it wrong?

We’ve taken the One out on road and trail rides over the last couple months.  We found it to be adequately ventilated for even the most stiflingly hot days (we get those in Colorado in February!) and comfortable in every configuration.

Overall, we like the Bollé One helmet for the biker who bikes a lot but not enough to buy multiple helmets.  It will do a good job of covering your dome on any bike you may ride.  Is it perfect for specific types of riding?  Well, no.  But the compromises aren’t enough to change the fact that it’s a good helmet that’ll save you up to $200.
