Love this helmet. Looks great, fits great, very comfortable and adjustable. Costly but a bargain as well. Highly recommend!

Until I actually wore a top of the line helmet I never knew what I was missing. Once I trimmed the cheekpads, I now have the perfect helmet! Lightweight, great airflow and very aerodynamic (even with the visor). Visibility is wide and clear. I ride in extreme heat and humidity, the XD4 provides lots of air flow. I highly recommend the XD4!

This was my first Aria helmet. The fit and construction is good, air flow is ok(could be better), and the only downside is the visor vibrates at speed and it translates to my earplugs in a seady streem of humming. It is a loud helmet with wind noise. Had to ready tighten down the visor mounting screws to reduce the vibration. The visor should be a bit more stiffer to eliminate the vibration. Overall a good helemt and would recomend it to adventure riders.
XD-4 .... worth every penny

I typically go for cheaper head gear that is still DOT/SNELL approved, but went well over what I have paid in the past for the XD-4. Is it worth it. Every penny! The venting on the helmet is quite decent, however I will need to have it out for a few hours in the heat to decide how well. Fit and finish are top notch, and this is the first helmet I have owned that actually seems to be designed to easily handle wearing sun glasses.
