As a person with a Round-Oval head shape I have struggled to find bicycle & motorcycle helmets that fit my head in the US market. My head also measures 59cm, which normally places me in-between a medium & large helmet with most manufacturers. This is not the case with this POC helmet! The Ventilation with this helmet is outstanding, much better than my out going Giro Aries Spherical helmet; plus the fit is much, much better than the Giro.
Love the contemporary styling of this helmet -- love the ALL WHITE color scheme too! Lots of air flow and is light on the head and neck, making riding more comfortable.
After a crash I had to retire my old POC helmet. Of course I could not find the same one. I took a chance with a new style (same brand) and it is... Awesome.
I really love the ventilation and comfort/fit. Great deal as well!
