By all accounts this is a great helmet. Ultimate I had to return it because of the fit. In my case the medium fits my head perfectly and is super comfy. The problem is with the straps which are WAY too short. The straps hit me in the ear and weren't long enough to buckle comfortably. It's almost as if they installed the straps for a size small helmet into the medium that I ordered. I tried the large but couldn't make it quite tight enough. My Octal in size medium fits brilliantly.
So - I really like the helmet. Looks great, feels great. The straps are just too short.
I bought this to replace my five year old Octal, which has been one of my favorite helmets. Unfortunately, while the Octal fit my large (size 7-58) head perfectly, the Ventral doesn't. There was barely enough room on the sides to put it on, and with a thin skullcap it was uncomfortably snug (winter hats would be out of the question).
I'm disappointed, because this is a great helmet.
