How is the fitment of the XD4 in comparison to the XD3?
I have been looking all over for a dealer in Minnesota that has yet to carry the XD4. All I can find to try on are XD3 helmets. How is the fitment of the 3 in comparison to the 4? A close enough match in size to make an online purchase without trying it on first?
I have not tried an Arai XD-3, but found the XD-4 to be quite narrow. I would not recommend it unless you have a narrow, long-oval shaped head. My Arai Vector - size XL - fits very well. But the XD-4 in the same size does not. I would refer you to my review.
