Not necessarily for everyone
Why would a helmet manufacturer that throws a huge amount of weight behind the Sky Professional Cycling Team, not take into account that nearly all of their riders are also Oakley sponsored? What I mean, is that if you are a dedicated Oakley wearer on the bike, then you'll need to look elsewhere for a helmet. I really wanted to like it - I really did. It fits great, is pretty comfortable, and has a great retention system. Unfortunately, I have multiple pair of Oakley Radars and they do NOT fit under this helmet. I was forced to stretch the arms of my glasses to fit over the retention system in the back, and invariably, this caused extra pressure (and eventual pain). In addition, the vents of this helmet will not hold glasses (if you sometimes take them off while riding and need a place to stick them).
I know that my choice of cycling glasses shouldn't be a reason to abandon a helmet, but I'm far more invested in Oakley than I am Kask. Hopefully this will help others considering this helmet. Back to Giro for me...
