People with high foreheads and narrow faces have what the helmet industry calls a "long oval" or "intermediate oval" head shape. Finding an ADV helmet that fits can be challenging, as not all models with desirable features are available in this shape. And there's no point in pretending otherwise--as I learned a few years ago. The Nolan modular helmet I had bought for its great features felt comfortable in the store. But after about an hour of riding, it caused an unbearable pressure on my forehead that was dangerously distracting, requiring frequent stops to remove the helmet for relief. The Nolan's shape simply didn't fit my head. Reluctantly, the helmet got relegated to the "loaner" shelf and the search for replacement began--about as much fun as filing taxes.
The Icon Variant proved to be a decent alternative. Although I chose basic white to keep my noggin cooler in the sun, the Variant's styling is good and there's a wide selection of graphics to choose from. Now that I've ridden in the Variant for a few seasons, I can attest to its comfort for long-oval heads. Other commendable features include the visor, which has decent optical properties and an excellent hydrophobic coating that causes all but the heaviest rain to bead off--almost as good as windshield wipers on a car. Ventilation is good, although the vent mechanisms can be a little sticky at times. The roost guard is effectively positioned and has surprisingly good aerodynamics at highway speeds.
Back to the filing taxes thing. What ADV helmet would fit? Previously I had ruled out Shoei, as my understanding was most of their helmets are aimed at rounder heads. But the Hornet X2 is aimed at medium oval, and fortunately my head is just within the range of its fit. Measured across my brow, my head circumference is 58.5cm and there's not much remaining hair to interfere with that measurement. This translates to a medium for the Hornet X2. It's tight, but not painfully so, and should loosen up slightly as the foam breaks in.
What's more, the Hornet is a lot quieter, there's less turbulent air in your face with the visor closed (meaning fewer bugs ricocheting up into your eyes from the chin region), the peak has even better aerodynamics, and there appears to be room for speakers without modifying the foam. Having now ridden in the Hornet for a few hours (at -2C to +5C, where you really notice the wind!), I'm happy to say it offers great visibility and performance, and probably higher overall safety given the quality of construction.
So far, so good. Hopefully it remains comfortable over the long term.
